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.
## What kind of change does this PR introduce?
UI improvements. Resolves DEPR-419.
## What is the current behavior?
- `ColumnList` splits type information across separate `Data Type` and
`Format` columns, which makes scanning less efficient
- The list only surfaces a limited subset of column metadata up front,
so key structural information like primary keys, foreign keys,
uniqueness, and identity is not easy to scan
- Constraint and nullability affordances are not aligned with the visual
language already used in the Table Editor and Schema Visualiser
## What is the new behavior?
- `ColumnList` now shows a leading type affordance icon, while keeping
the exact Postgres type visible in the `Type` column
- The standalone `Data Type` column is removed, and `format` is now the
primary textual type shown in the table
- The `Constraints` column now surfaces explicit icon-plus-label tokens
for:
- `Primary`
- `Foreign key`
- `Unique`
- `Identity`
- `Nullable` / `Non-nullable`
- Constraint tokens use a purpose-built segmented style based on
`ComputeBadge`, including a green primary variant for primary keys
- Nullability now matches Schema Visualiser semantics exactly: outlined
diamond for nullable, filled diamond for non-nullable
- Existing search, descriptions, row actions, and permission gating are
preserved
