feat: add ticket numbers to cards with workspace prefix (#443)

* feat: add ticket numbers to cards with workspace prefix

- Add cardNumber to cards
- Add cardPrefix/cardCounter to workspace
- Populate initial prefixes and numbers via new migration
- Introduce generateWorkspacePrefix util and export it
- Include cardNumber in card-related API responses and search results
- Render and display tickets as PREFIX-NUMBER in UI
- Update Card component to accept ticketNumber
- Update CardModal and board cards to show number when available
- Add cardNumber to CommandPalette search results type

* feat: regen migration

* feat: enhance card and workspace schemas with cardNumber and indexing

- Updated the card repository to allocate card numbers atomically per workspace.
- Modified the card schema to include a cardNumber field and added an index on listId and cardNumber for improved query performance.
- Enhanced the workspace schema to include an index on cardPrefix for optimized lookups.
- Adjusted the migration journal to reflect the new schema changes and their timestamps.
- Updated the regex in workspace repository to allow alphanumeric prefixes in ticket IDs.
