Danny White 7a77760a10 fix(studio): confirm before discarding dirty replication destination forms (#48522)
## What kind of change does this PR introduce?

Bug fix (dirty form dismissal for Replication destination sheets), plus
small docs/skill updates so agents pick up the existing modality
pattern.

## What is the current behavior?

Closing the Add/Edit destination sheet (Cancel, Escape, or backdrop)
discards in-progress form state with no confirm. Same for the nested
Create publication sheet.

## What is the new behavior?

Dirty closes go through `useConfirmOnClose` +
`DiscardChangesConfirmationDialog`, matching other Studio sheets.
Successful submit still closes without prompting.

Also: skills + `forms.mdx` now point at Modality “Dirty form dismissal”.

### How to test

1. Studio → Database → Replication → **Add destination** (any pipelines
type with access).
2. Change a field so the form is dirty.
3. Try Cancel, Escape, and backdrop click → discard dialog appears;
**Keep editing** stays open; **Discard changes** closes.
4. Submit successfully with a valid config → sheet closes with no
discard dialog.
5. Repeat for **Edit destination** from a destination row menu.
6. Optional: Add destination → create a new publication from the
publication picker → dirty that nested sheet and dismiss the same way.
7. Optional: Add destination → Read Replica → change region → dismiss →
discard dialog; deploy still closes without prompting.

## Additional context

Sheet owns the close guard; forms report dirty via a ref because RHF
lives in the child. Nested `NewPublicationPanel` wires the guard
locally.
