feat: tool permission toggles, settings improvements, UI polish

- Tool permissions (read, edit, bash) stored in DB and control Agent tool registration
- Agent invalidated when permissions change; cache warning in Permissions panel
- Default: read=allow, edit=ask, bash=ask (matches UI checkboxes)
- Settings: auto-save title model on selection (removed save button)
- Settings: auto-expand thinking checkbox with shared reactive store
- Permissions panel: renamed from Permission Log, shows tool toggles + collapsible log
- Sidebar: renamed Current Model to Model Choice
- Chat input: allow typing while agent runs (just disable send)
- Chat cursor: fix doubled rectangle (removed unicode char)
- Generic GET/PUT /tabs/settings/:key endpoints for key-value settings
