Add enable/disable management for book tools (characters, worlds, and locations)

- Introduced toggling functionality for managing `characters`, `worlds`, and `locations` tool availability per book.
- Updated `CharacterComponent`, `WorldSetting`, and `LocationComponent` with toggle switches for tool enablement.
- Added `book_tools` database table and related schema migration for storing tool settings.
- Extended API calls, models, and IPC handlers to support tool enablement states.
- Localized new strings for English with supporting descriptions and messages.
- Adjusted conditional rendering logic across components to respect tool enablement.
