fix: handle special char search 500 & polish live badge (#144)

* fix(search): handle numeric query FTS errors regardless of table existence

Remove the `no such table: messages_fts` condition so numeric queries
fall back to LIKE search on any FTS failure (malformed MATCH, missing
table, etc.).

* fix(search): handle special char queries, polish live badge UI

- Add hasUnsafeChars() to catch FTS5-breaking queries (¥, @, #, etc.)
  and fall back to LIKE search, preventing 500 errors
- Polish session live badge: smaller size, remove border/shadow,
  add pulsing dot indicator for a cleaner look
- Remove spinner drop-shadow glow effect
