Towards [FE-3428](https://linear.app/supabase/issue/FE-3428).
## Summary
Cheap render-cost fixes so the Schema Visualizer stays responsive at
400+ tables. No data-layer or API changes — pure render-side work,
isolated to the Schema Visualizer.
- Enable `onlyRenderVisibleElements` on `<ReactFlow>` so xyflow skips
mounting nodes and edges outside the viewport.
- Memoize `TableNode` (custom comparator) and `DefaultEdge` so they
don't re-render on unrelated state changes (pan/zoom, theme toggle,
parent re-renders).
- Drop `resolvedTheme` from the layout effect deps — theme is purely
visual; toggling it no longer re-runs Dagre and replaces every
node/edge.
- `handleSelectionChange` now (a) skips `setEdges` entirely when no
edge's `animated` flipped, and (b) preserves the object reference for
untouched edges so memoized edges don't re-render.
- Precompute a `Map<tableName, …>` lookup in `getGraphDataFromTables` so
FK handle resolution is O(1) per relationship instead of scanning every
table+column.
A follow-up PR will add a `useInfiniteTablesQuery` and switch both the
Schema Visualizer and Database > Tables list onto it for progressive
loading and infinite scroll.
## Caveats
- `TableNode` reads `selectedEdge` from context, so selecting an edge
still re-renders all visible `TableNode`s via context propagation. The
memo guards against props-driven re-renders (pan/zoom/theme).

## Summary by CodeRabbit
* **Refactor**
* Optimized database schema graph rendering with improved component
caching and efficient relationship lookups.
* Enhanced visual element rendering to reduce unnecessary re-renders for
large schemas.

This PR migrates the whole monorepo to use Tailwind v4:
- Removed `@tailwindcss/container-queries` plugin since it's included by
default in v4,
- Bump all instances of Tailwind to v4. Made minimal changes to the
shared config to remove non-supported features (`alpha` mentions),
- Migrate all apps to be compatible with v4 configs,
- Fix the `typography.css` import in 3 apps,
- Add missing rules which were included by default in v3,
- Run `pnpm dlx @tailwindcss/upgrade` on all apps, which renames a lot
of classes
- Rename all misnamed classes according to
https://tailwindcss.com/docs/upgrade-guide#renamed-utilities in all
apps.

This PR preps the monorepo for a migration to Tailwind v4:
- Bump all Tailwind dependencies and libraries to the latest possible
version, while still compatible with Tailwind 3.
- Cleans up obsolete Tailwind 3 specific options and configs.
- Cleans up unused CSS files and fixes the CSS imports.
- Migrates all `important` uses in `@apply` lines to using the `!`
prefix.
- Move `typography.css` to the `config` package and import it from the
apps.
- Migrated all occurrences of `flex-grow`, `flex-shrink`,
`overflow-clip` and `overflow-ellipsis` since they're deprecated and
will be removed in Tailwind 4.
- Make the default theme object typesafe in the `ui` package.
- Migrate all `bg-opacity`, `border-opacity`, `ring-opacity` and
`divider-opacity` to the new format where they're declared as part of
the property color.
- Bump and unify all imports of `postcss` dependency.
## Problem
When using LLMs, it's useful to describe your tables in markdown format.
## Solution
- Add an _Copy as SQL_ and _Copy as Markdown_ in the schema visualiser
table menu

/>
- Refactor the _Copy as SQL_ and _Download current view_ buttons in a
single button/dropdown combo and add _Copy as markdown_:

## Problem
When you have many tables, it's hard to follow the relations between
them in the Schema Visualiser
## Solution
When selecting an edge (the line between tables), highlight it along
with the related tables and columns to make it easier.
Also, if there is enough space, display a popover showing the relation
details
## Screencasts

## Problem
- The schema visualiser lacks editing capabilities which leads to a lot
of navigation (ediing tables, columns)
- ReactFlow prevents users from selecting table and column names (to
copy them). Diasbling drag and pan on those texts would make moving
items cumbersome
- Long table and column names are hidden and even hide other elements
## Solution
- Add menus for both tables and columns
- Truncate long names with ellipsis and add a tooltip
- Hide menus when exporting to png/svg

## Problem
Editing a column from the schema visualiser requires many clicks
## Solution
When hovering over a column in the schema visualiser, an edit button
should appear on the right side. Clicking this button should open the
column edit pane on the right side of the screen. This would reduce the
number of clicks required and allow users to make edits directly from
the visualiser instead of using it only as a visual aid.
