Hide any field

### Checks

- [x] I have read the Wiki, searched the open issues, and still think this is a new feature.

### Explain the problem clearly and succinctly:

For some DBs, certain fields are not needed and clutter the UI.

### Describe the solution you'd like:

Please allow hiding any field (per DB or globally in the app). Thanks

### Describe alternatives you've considered:

_No response_

### Additional context:

_No response_

The issue names no files, tests, or entry points. Start by clarifying whether field hiding is per database or global, and which fields are in scope. Done would require an agreed behavior for both configuration options and validation that hidden fields no longer clutter the UI.
