feat(ui): add visual indicator for recently updated repositories

This commit introduces a "hot" indicator (🔥) for repositories updated within the last week and cleans up unused resources and time formatting logic.

- **feat(ui)**: Updated `RepositoryCard` to prepend a fire emoji to the release date if the repository was updated within the last 7 days.
- **refactor(core)**: Introduced `hasWeekNotPassed` utility in `TimeFormatters.kt` to check repository update freshness.
- **refactor(core)**: Removed unused `formatUpdatedAt` functions and simplified `TimeFormatters.kt`.
- **chore(android)**: Removed default Android launcher background and foreground vector drawables.
- **chore**: Cleaned up unused imports and Material3 Experimental APIs in `RepositoryCard.kt`.
