Description

This PR adds a new FireDataStore, which allows to store automatic and manual data-clearing options. There is a new FireClearOption enum that has 3 options: TABS, DATA and DUCKAI_CHATS.

Steps to test this PR

• Make sure the unit tests pass

---

Note

Adds a DataStore-backed FireDataStore to manage manual and automatic clear options (incl. when), a new FireClearOption enum, DI module, and unit tests with legacy settings migration.

• Fire clearing storage:
  • Add FireDataStore interface and SharedPreferencesFireDataStore implementation backed by DataStore<Preferences>.
  • Manage separate option sets for manual and automatic clearing: flows, getters, setters, add/remove, and selection checks.
  • Persist "when to clear" via getAutomaticallyClearWhenOption* with migration from legacy SettingsDataStore (ClearWhatOption, ClearWhenOption).
  • Parse/validate persisted enums; default manual options to TABS + DATA and fallback to legacy for automatic.
• DI/Module:
  • Provide qualified @FireData DataStore via FireDataStoreModule using preferencesDataStore (fire_clearing_preferences).
• Models:
  • Introduce FireClearOption enum: TABS, DATA, DUCKAI_CHATS.
• Tests:
  • Add comprehensive unit tests covering flows, add/remove, independence of manual vs automatic sets, and legacy migration for both "what" and "when".
