feat(dashboard): bulk restore and make permanent for memories (issue 676)

[ICEY16360]

Approved issue: #676

What

Adds Restore and Make permanent to the Memories bulk-action bar, so a selection can be brought back from archived (or lifted to permanent) in one command. The backend already supports both: bulk_update_memory_status accepts any status, treats a change into active/permanent as a restore for epoch-bump purposes, and only bumps for rows whose status actually changes.

Changes

• packages/dashboard/src/components/MemoryBrowser/MemoryBrowser.tsx: handleBulkRestore / handleBulkPermanent mirroring handleBulkArchive (confirm → bulkUpdateMemoryStatus → clear selection → refetch), plus Restore and Make permanent buttons next to Archive. Confirm dialogs mirror the Archive one, including the singular/plural template.
• packages/dashboard/src-tauri/tests/db_mutations.rs: bulk_restore_mixed_selection_changes_and_bumps_only_actually_changed_rows — a mixed selection (archived→active and permanent→active that change, active→active no-ops, including one project path with no changes at all) asserts only the transitioning rows change, only their paths bump the epoch, and a restore queues no memory mutations.
• packages/docs/src/content/docs/reference/dashboard.md: the bulk-select line now lists restore and make permanent.

No production Rust change — the approved shape is frontend plus a test of the existing command.

Harness coverage (required)

• OpenCode 1: covered — shared dashboard over the shared context.db
• OpenCode 2: covered — same dashboard
• Pi: covered — same dashboard; Pi shares the store
• OMP: covered — same dashboard
• Rust module: covered — new integration test in db_mutations.rs exercises bulk_update_memory_status's no-op guard and epoch semantics (no production Rust change)

Summary by cubic

Adds Restore and Make permanent to the Memories bulk-action bar, so a selection can be brought back from archived or lifted to permanent in one command, alongside the existing Archive and Delete.

• The backend already supports both via bulk_update_memory_status; only frontend, tests, and docs change.
• Confirm dialogs mirror the Archive flow; Restore warns when selected permanent memories would lose never-expire status.
• Selection is pruned whenever a refetch drops selected rows from the visible list, so bulk actions never act on rows the user can no longer see.
• New integration tests cover restore-to-active and make-permanent: only rows that actually change status bump the epoch, and neither queues memory mutations.
• The bulk-action bar now wraps on narrow windows, and the dashboard docs list the new actions.

^{Written for commit effa624. Summary will update on new commits.}

Confidence Score: 5/5

The PR appears safe to merge, with no outstanding findings.
