[Feature Request]: Logical Database Aliases and Metadata (Description, Tags)

Problem

Logical databases (db0, db1, ...) are only shown by numeric index. In real projects each index serves a different purpose (sessions, cache, queues, etc.), but there's no way to tell which is which without digging through docs or code.

Proposal

Let users assign an alias, short description, and optional tags to each logical database (via UI and/or a shareable config file, e.g. redis-db-map.json).

Instead of manually typing/selecting the DB by index, show a dropdown/list of logical databases (by alias) when switching databases.

Example

Benefits

• Faster onboarding, fewer mistakes (wrong DB selected)
• Self-documenting database browser
• Config file can be shared/versioned across the team

The issue names no files, tests, or entry points. Start by locating the logical database selector and any existing configuration handling, then clarify whether the scope includes UI metadata, a shareable config file, or both; done means aliases, descriptions, tags, and alias-based database selection have an agreed design and coverage.
