Editor panel fix save snippet (#50262)

## Context

Currently hitting "Save snippet" in the Editor panel doesn't actually do
anything - happening because it's using the legacy `needSaving` queue
logic that we had before manual saving became the default. Tiny fix to
just call `requestSave` instead

## Summary by CodeRabbit

- **Improvements**
- Saving a snippet now updates the SQL editor with the latest content
automatically.
- New snippets created from the expanded editor or save dialog are saved
through the standard save flow.

- **Accessibility**
- Added an accessible label to the snippet name field for improved
screen reader support.
