feat(reader): 船新的基于 Compose 实现的阅读菜单界面与各项优化

* 初始版本

* refactor(reader): MVI architecture + menu settings overhaul

MVI/UDF Architecture:
- Add ReadBookContract: UiState, Intent, Effect, Sheet, Dialog, ConfigUpdate
- Refactor ReadBookViewModel with onIntent() entry point
- Add ReadBookScreen/ReadBookRouteScreen stateless composables
- Add ReadBookColorTheme for reader-specific theme override
- Add ReadConfigContract for read config screen MVI

ReadStyleSheet Decomposition:
- Split ReadStyleSheet into SystemMenuPage, TextTitleSheet,
  HeaderFooterPage, TitleBarIconSheet, GlobalThemePage
- Each page owns its tab state, color picker, and config mutations

Data Layer (DataStore-backed Repositories):
- Add ReadSettingsRepository with ReadPreferences flow
- Add MangaSettingsRepository with MangaPreferences flow
- Add ReadAloudSettingsRepository for TTS settings
- Add ReadStyleRepository (file I/O for read style configs)
- Add ReadBookStyleConfigRepository (repository boundary)
- Add ReadStyleResolver for background/theme resolution
- Remove legacy ReadTipConfig (merged into ReadBookConfig)
- Register all new repositories in Koin appModule

Menu Settings:
- Add unified border settings (width, color, colorNight) for
  both top and bottom bars with drawWithCache + drawPath
- Add ColorModePill with light/dark toggle and '+' icon for
  no-color state in TinySettingItems
- Add TinyClearColorModeSettingItem for border color config
- Add menu color customization (bg, accent, container) with
  day/night variants and seed color mode
- Add bottom bar layout settings (corner radius, margins)
- Add custom icon support for menu buttons and title bar icons
- Add title bar icon position setting

Config Pipeline:
- Consolidate all ReadBookConfig mutations into typed ConfigUpdate
  sealed interface with legacy UP_CONFIG code mapping
- Add resolvedMenuBorderColor (auto day/night switching)
- Add 20 new PreferKey constants for menu settings
- Update manga config dialogs to use MangaSettingsRepository
- Update ReadConfigViewModel with DataStore flow observation

* feat(reader): add liquid glass menu bars and floating bottom bar

- Integrate com.kyant.backdrop 2.0.0 for liquid glass blur/vibrancy
  effects on reading menu top bar and bottom bar (Android 13+)
- Add floating bottom bar toggle replacing manual margin sliders
- Extract ReadMenuConfig data class for proper MVI state management
  of all menu configuration properties
- Enable edge-to-edge in BaseComposeActivity, remove manual
  navigation bar color management across base classes and controller
- Fix fullScreen() to use setDecorFitsSystemWindows(false)

* Refactor series button rendering

* 实现液态玻璃

* 优化液态玻璃

fix(reader): fix MVI behavior issues and improve sheet lifecycle

Behavior fixes:
- Fix AddSourceAsNewBook empty implementation — wire intent to addToBookshelf
- Fix content edit loading stuck on null chapter/content — use onFinally
- Fix cannot save empty content — remove isEmpty guard, use title as loaded proxy
- Fix bookmark not opening — use openReadMenuRoute instead of dead activeSheet path
- Fix chapter source sheet persists — animate dismiss via show param before removal
- Fix chapter source reopens to TOC — reset showToc in initData
- Fix SaveChapterContent saves to wrong chapter — carry chapterIndex in intent
- Fix chapter source search runs after dismiss — cancel searchJob in dispose
- Fix "go to background" button in ReadAloud — use CloseReadBook intent

Architecture improvements:
- ReadMenuConfig uses ImmutableMap for Compose stability
- Fix stale remember in ReadBookMenuBar title bar icons
- Move icon picker file IO from composable to ViewModel
- Route launcher results through MVI intents instead of direct calls
- Fix ChangeChapterSource effect collector key — use viewModel not Unit
- Make ReadAloudConfigSheet UDF-compliant — stateless with intents
- Remove main menu buttons from AutoRead and ReadAloud sheets

  ConfirmDismissButtonsRow for save/cancel buttons
- SystemMenuPage MenuCustomIconSheet: same icon and button treatment

  instead of drawable resource Int
- Use AutoMirrored variants for List and HelpOutline icons
