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

* 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
