fix(dashboard): replace hover row-actions with kebab menu, fix modal button reset and delete color

- Bug 1: hover actions covered total column; replaced with kebab dropdown in dedicated 44px column
- Bug 2: resync/delete buttons kept stale state across modal opens; reset in modal init block
- Bug 3: delete success button was green (btn-success); changed to red (btn-danger)
- Dropdown styled per DESIGN.md: warm shadow, 8px radius, dark mode tokens
