Problem

Parent: #718

Small connection-tile / leaf parity leftovers:

1. Extension — context menu has Edit/Remove only (no Refresh); selected name uses w600/w500 unlike other drivers.
2. SQLite — subtitle shows host only; network drivers show host:port (subtitle column misaligns).
3. Redis — DB rows omit connection on _PgTreeRow → no tree context menu (Mongo DB rows have one).

Proposal

1. Add Refresh on Extension tile (reload SDUI roots / session) matching other drivers.
2. Normalize Extension title TextStyle with PG/MySQL tiles.
3. SQLite: show path/host consistently (or explicit “file” subtitle pattern used by all file DBs).
4. Pass connection into Redis DB _PgTreeRow for Copy name / Refresh patterns.

Files

• connections_panel_extension.dart
• connections_panel_sqlite.dart
• connections_panel_redis.dart

Acceptance

• Extension has Refresh + matching title weight
• SQLite subtitle column aligns with other tiles
• Redis DB rows expose the same baseline context menu as Mongo DB rows
