fix: help banners no longer show up in the wrong editor section (#9609)
#### Brief overview of PR changes/additions
- Switching editor sections now clears the previous section's help
banner instead of leaving it over the new section
- Clicking X on the "Banner hidden. Undo" toast now just closes the
toast instead of suppressing every banner for that view
- Error/warning messages survive a section switch and are no longer
hidden by a leftover toast expiry timer
- Adds EditorBannerViewSwitchTest covering the repro and undo behaviour

#### Motivation for adding to Mudlet
Dismissing a banner then switching sections could show e.g. timer help
in the scripts section, confusing users.

#### Other info (issues closed, discussion etc)
Assisted-by: Claude:claude-fable-5

**Test case:** Open editor, Scripts, click X on the banner twice, open
Timers, back to Scripts - no stale Timers banner appears.

#### Demo

* Regression tests for the editor's dismissible help banners when switching
