feat: expand character editor to show all v2/v3 character card fields

Added support for all v2/v3 character card fields in the character editor UI:
- Description (10-row textarea)
- Scenario
- Message Example
- Post-History Instructions
- Alternate Greetings (one per line)
- Tags (comma-separated)
- Creator
- Character Version
- Creator Notes

Updated frontend to load and save all fields, and backend update_character
command to accept all new parameters. This allows imported v3 character cards
to display their full details, especially the description field which contains
the main character information.
