feat: remove quick reply, streamline blog reply (v2.7.0)

Remove the quick-reply code path entirely — all replies now go through
Micropub as blog posts. Quick replies created orphan URLs that served
raw JSON-LD to browsers and caused unreadable links in conversations.

- Delete quick-reply controller (note-object.js) and route
- Remove ap_notes collection registration
- Simplify compose form: no mode toggle, no character counter
- Remove quick-reply CSS and locale strings
