fix(workspace): sort daily memory by date and inline into file grid

- Sort daily memory list by filename (YYYY-MM-DD.md) instead of mtime
  so editing an older file no longer bumps it to the top
- Move daily memory card inline with workspace MD file buttons
- Shorten card description across all locales
- Defer file creation until user actually saves (no empty file on create)
