refactor: simplify Profile feature state management and update ViewModel

* Add uncaught exception handler that saves stacktraces to local crash log files
* Show a Compose crash dialog with stacktrace toggle and share action
* Register crash handler activity in a separate process with dialog theme
* Remove ACRA dependencies and configuration
* Add crash dialog strings and ignore `.hotswan/`

-# Fast Messenger Tech Debt Audit
-
-## Critical
-
-### `core/network/src/main/kotlin/dev/meloda/fast/network/interceptor/Error14HandlingInterceptor.kt`
-- captcha flow is built around `wait/notify`, a raw executor, and shared mutable state.
-- risk: deadlocks, leaked jobs, hard-to-reproduce auth hangs.
-- fix: rewrite as suspend-based flow with timeout and explicit cancellation.
-
-### `core/domain/src/main/kotlin/dev/meloda/fast/domain/LongPollEventParser.kt`
-- file mixes parsing, dispatching, IO loading, and concurrency orchestration.
-- risk: regressions when VK event format changes.
-- fix: split by event family and add parser tests.
-
-### `feature/messageshistory/src/main/kotlin/dev/meloda/fast/messageshistory/MessagesHistoryViewModelImpl.kt`
-- view model is doing too much: loaders, navigation, selection, long poll hooks, read peers, dialog flow.
-- risk: brittle state transitions and untestable branching.
-- fix: extract coordinators/handlers per concern.
-
-### `app/src/main/kotlin/dev/meloda/fast/MainViewModel.kt`
-- root bootstrap handles auth, locale, long poll, permissions, profile, and start destination in one class.
-- risk: startup bugs and hidden coupling between flows.
-- fix: move startup/permission orchestration into dedicated controllers.
-
-### `app/src/main/kotlin/dev/meloda/fast/presentation/RootScreen.kt`
-- root composable owns too many top-level flows and dialogs.
-- risk: UI orchestration drift and hard-to-read navigation logic.
-- fix: split dialogs, bootstrap, and navigation concern into smaller composables.
-
-## High
-
-### `core/domain/src/main/kotlin/dev/meloda/fast/domain/LongPollEventParser.kt`
-- uses many `Log.d` calls and large `when` branches.
-- fix: reduce logging noise and add structured tracing only where needed.
-
-### `core/network/src/main/kotlin/dev/meloda/fast/network/ResponseConverterFactory.kt`
-- double-parsing response bodies and only logging malformed payloads.
-- risk: opaque failures and harder debugging.
-- fix: normalize error conversion and surface typed failures.
-
-### `feature/profile/src/main/kotlin/dev/meloda/fast/profile/ProfileViewModel.kt`
-- `loadAccountInfo()` has an empty error branch.
-- risk: profile can fail silently.
-- fix: set `baseError` and show fallback UI.
-
-### `feature/messageshistory/src/main/kotlin/dev/meloda/fast/messageshistory/presentation/attachments/Attachments.kt`
-- attachment preview logic still sits in UI layer and mixes fallback behavior.
-- risk: silent drops of unsupported attachments.
-- fix: move preview mapping to domain/ui-model layer.
-
-### `feature/messageshistory/src/main/kotlin/dev/meloda/fast/messageshistory/presentation/Link.kt`
-- title handling is nullable and duplicated with preview logic.
-- fix: create a small UI model for link rendering.
-
-### `feature/messageshistory/src/main/kotlin/dev/meloda/fast/messageshistory/presentation/File.kt`
-- preview extraction is inline and branches on raw model internals.
-- fix: extract to mapper/UI model.
-
-### `feature/messageshistory/src/main/kotlin/dev/meloda/fast/messageshistory/presentation/MessagesList.kt`
-- message-item interaction is dense and repeated.
-- fix: normalize scroll/reply handlers and reduce nested callbacks.
-
-## Medium
-
-### `core/data/src/main/kotlin/dev/meloda/fast/data/VkUsersMap.kt`
-- lookup helpers were using unsafe assumptions on external data.
-- status: already improved, but should stay covered by tests.
-
-### `core/data/src/main/kotlin/dev/meloda/fast/data/VkGroupsMap.kt`
-- same risk profile as users map.
-- status: already improved, still needs tests.
-
-### `core/domain/src/main/kotlin/dev/meloda/fast/domain/OAuthUseCaseImpl.kt`
-- auth success mapping used forced unwraps on server data.
-- status: already improved, but auth contract should be validated.
-
-### `app/src/main/kotlin/dev/meloda/fast/presentation/MainActivity.kt`
-- service lifecycle now respects config changes, but app exit semantics should be documented.
-- fix: keep explicit separation of app-close vs config-change behavior.
-
-### `build-logic/convention/src/main/kotlin/dev/meloda/fast/KotlinAndroid.kt`
-- build-tools are pinned to the local environment.
-- risk: portable builds may drift between machines.
-- fix: prefer SDK-managed consistency or document required SDK version.
-
-### `app/src/main/kotlin/dev/meloda/fast/presentation/RootErrorDialog.kt`
-- currently hardcodes English strings for some errors.
-- fix: localize all texts through resources.
-
-### `app/src/main/kotlin/dev/meloda/fast/presentation/RootScreen.kt`
-- root-level error dialog is better, but some orchestration still remains in the root composable.
-- fix: split into smaller root flows over time.
-
-## Low
-
-### `core/ui/src/main/kotlin/dev/meloda/fast/ui/components/AnimatedDots.kt`
-- marked TODO rewrite.
-- fix when touching related loading UI.
-
-### `core/ui/src/main/kotlin/dev/meloda/fast/ui/theme/AppTheme.kt`
-- color picker TODO suggests unfinished theme customization.
-
-### `core/model/src/main/kotlin/dev/meloda/fast/model/api/data/LongPollUpdates.kt`
-- `List<List<Any>>` is a weakly typed API boundary.
-- fix: introduce explicit event DTOs.
-
-### `core/model/src/main/kotlin/dev/meloda/fast/model/api/domain/VkMessage.kt`
-- attachment persistence is still a TODO area.
-
-### `core/model/src/main/kotlin/dev/meloda/fast/model/database/VkMessageEntity.kt`
-- attachment storage/restoration is unresolved.
-
-### `core/common/src/main/kotlin/dev/meloda/fast/common/model/LongPollState.kt`
-- Android 15 support TODO.
-
-### `feature/messageshistory/src/main/kotlin/dev/meloda/fast/messageshistory/MessagesHistoryViewModelImpl.kt`
-- large commented-out legacy block should be removed once upload flow is reimplemented.
-
-### `feature/auth/src/main/kotlin/dev/meloda/fast/auth/login/LoginViewModel.kt`
-- debug/auth token acquisition TODO indicates unfinished auth path.
-
-## What To Do First
-1. Rewrite captcha interceptor.
-2. Split `LongPollEventParser`.
-3. Extract `MessagesHistoryViewModelImpl` orchestration.
-4. Localize `RootErrorDialog` strings.
-5. Add tests for auth, long poll parsing, and attachment mapping.
-
-## Note
-- Current code is already better on crash-prone nullable handling and service lifecycle.
-- Remaining work is mostly structural and testability-focused.
