## Context
Saves the last visited explorer tab via `useDashboardHistory`, such that
landing back on `/explorer` will open the last visited page. Similar
behaviour to Table Editor and SQL Editor
Would also be useful when going between the SQL Editor and Explorer to
bring snippets over

## Summary by CodeRabbit
* **New Features**
* Explorer now remembers and restores the last visited query, chat, or
notebook tab.
* Automatically returns to the Explorer home screen when a saved tab is
unavailable.
* Displays a loading state while the last visited tab is being restored.
* **Bug Fixes**
* Closing deleted chat tabs now clears their saved history.
* **Tests**
* Added coverage for Explorer tab restoration, loading states, and stale
history cleanup.

App-level fixes that reproduce on BOTH the Next and TanStack builds —
split out of #47657 (which stays TanStack-only) for reviewability. All
were found by a full-site click-through of the dashboard.
## Invalid HTML nesting (React 19 "will cause a hydration error" console
errors)
- **FormLayout description rendered in a `<p>`**
(`packages/ui-patterns`): consumers pass arbitrary JSX (the RowEditor's
`created_at` timezone note passes a `<div>` with `<p>`s) →
`<p>`-in-`<p>` / `<div>`-in-`<p>`. Container is now a `<div>` with
identical classes (Tailwind preflight makes them render the same).
- **Switch toggles nested inside Tooltip trigger buttons**
(button-in-button) in ColumnEditor ("Allow Nullable" + "Is Unique"),
ExtensionRow, and PublicationsTableItem → repo-standard `TooltipTrigger
asChild` + `<div>` wrapper.
- **Saved log queries rendered a `<div>` directly inside `<tbody>`**
(`/logs/explorer/saved`) → rows are now proper `<tr><td colSpan>`
wrappers; the component itself is untouched (it's valid in its sidebar
usage).
- **Nested anchors in observability metric cards**: a card-level
`<Link>` wrapped MetricCard's "More information" `<Link>` (identical
URLs) → the chevron affordance renders as a `<span>` when no `href` is
passed; clicks bubble to the card link, tooltips preserved.
Design-system standalone usage unaffected.
- **`objectFit="cover"` passed to modern `next/image`** on the featured
integration card (unknown-prop warning) — the className already had
`object-cover`; prop dropped.
## Ghost dead-snippet after deletion
Deleting the active SQL snippet left its id in `useDashboardHistory`
(`history.sql`), so the "SQL Editor" nav item navigated to
`/sql/<deleted-id>` — content fetch 404s, no editor pane renders, and a
phantom tab reappears. Fixed both ends: delete flows now purge dashboard
history (and the tabs store clears a stale `previewTabId`), and
`/sql/[id]` treats a snippet 404 as "clean up + `router.replace` to
`/sql/new` + toast" instead of rendering the dead state. Unit tests for
the store/history cleanup.
## `pg-meta` migrations query 400s on every project load
`ActivityStats` on project home runs the migrations list query, whose
SQL was a bare `select * from supabase_migrations.schema_migrations` —
that table only exists once a migration has run, so every other project
logged a failed `?key=migrations` request on every load (visible in
production consoles too). The SQL is now guarded with `to_regclass` +
`query_to_xml` (same pattern as the advisor lints' `storage.buckets`
guard), returning zero rows instead of erroring; legacy version-only
tables still work. Tested against real dockerized Postgres (absent
table, populated ordering, special chars, legacy schema) + MSW hook
tests.
Found and verified via /test-supabase-local (browser click-through +
console audit on both builds).
## To test
Console must stay free of React DOM-nesting errors ("cannot be a
descendant of" / "cannot contain a nested") on each surface:
1. Table editor → Insert row panel (`created_at` field renders its
timezone note) and Edit column panel ("Allow Nullable"/"Is Unique"
tooltips still hover).
2. `/database/extensions` and `/database/publications` → toggle switches
render, tooltips hover.
3. `/logs/explorer/saved` (with ≥1 saved query) → rows render full-width
inside the table, hover shows Actions.
4. `/observability` → no nested-anchor error on load; card body click
and the chevron both navigate; label help-icons still show tooltips.
5. `/integrations` → no `objectFit` unknown-prop warning; featured card
images still cover.
6. **Ghost snippet**: open a SQL snippet → delete it via the sidebar →
click the "SQL Editor" nav item → lands on `/sql/new` (no phantom tab,
no 404 content fetch). Direct-load `/sql/<random-uuid>` → toast +
redirect to `/sql/new`.
7. **Migrations 400**: load project home with a project that has never
run a migration → the `pg-meta/<ref>/query?key=migrations` request
returns **200** with `[]` (previously a 400 on every load). Database →
Migrations still lists real migrations when they exist.

## Summary by CodeRabbit
* **Bug Fixes**
* Deleted SQL snippets are fully removed from dashboard history and
stale editor/tab state; users are redirected with a toast.
* Closing preview tabs no longer leaves stale references.
* Improved toggle/tooltip/dialog interactions to avoid broken UI,
including metric headers showing tooltips even without direct links.
* Migrations display safely when migration tables/relations are missing.
* **UI Improvements**
* Refreshed layout for saved queries, form descriptions, and integration
imagery.
* **Tests**
* Added coverage for snippet history cleanup, tab removal, migrations
SQL behavior, and query edge cases.

### Review feedback: `query_to_xml` breaks on Multigres (Ivan)
The defensive migrations query (added here to stop the `?key=migrations`
400 when the table doesn't exist yet) originally guarded with
`query_to_xml`, which is forbidden through Multigres's pooler (MUL-736 /
PSQL-1318). Rewritten without `query_to_xml`/`xmltable` using the
splinter#170 pattern: a PL/pgSQL `do` block guarded by `to_regclass`
(PL/pgSQL defers planning, so a missing table never errors) stashes the
rows into a transaction-local GUC via `set_config`, and a trailing
`select` reads them back with `jsonb_array_elements`. Verified that
postgres-meta sends the whole SQL as one simple-query string → single
implicit transaction → the local GUC survives to the `select` and
doesn't leak into the pooled connection. 6/6 dockerized-Postgres tests
(absent table → `[]`, populated/ordered/special-chars, legacy
version-only table, full pg-meta-shaped multi-statement string, GUC
non-leakage).
Note (out of scope, pre-existing):
`packages/pg-meta/src/sql/studio/advisor/lints.ts` still uses
`query_to_xml` — a separate pre-existing Multigres risk that should get
its own splinter-pattern sync.
