Reading database constraint errors the admin can explain to a user.

Display roles for the admin overview (ADR-040).

A field's role says what its value is to a reader — a relation, money, a
due date — and decides how a list cell renders it. Roles are derived from
the field's type, its name and the entity's relations; an explicit
`:display` in the field config wins. Pure: config in, data out.

What an entity form shows, which of a form's errors it cannot show next
to a field, and the child rows a parent is created with (BOU-570).

Who may do what in the admin, as pure decisions.

Under `:wagoe/authorization :mode :off` and `:report` today's rule
decides: the `:admin` role. Under `:enforce` the user's rights do
(ADR-041 §6): `admin.<entity>/read` to see an entity, `admin.<entity>/write`
to change it, each held in scopes the entity can check. A platform admin
holds everything, everywhere.

The shell puts the request's rights on the user map under `::access`
(`with-access`); a user without it is decided by the role.

Pure functions for database schema introspection and entity configuration.

This namespace contains pure business logic for transforming raw database
metadata into UI-friendly entity configurations. All functions are pure
(no side effects) and testable without database connections.

Key responsibilities:
- Parse database column metadata into field configurations
- Infer appropriate UI widgets from database types
- Detect relationships and foreign keys
- Merge auto-detected configuration with manual overrides
- Generate sensible defaults for labels and field ordering

Admin UI components using Hiccup for server-side HTML generation.

This namespace is a thin FACADE: the implementation lives in focused
sibling namespaces under `wagoe.admin.core.ui.*`. Every public function
consumers rely on is re-exported here so `admin-ui/entity-list-page`,
`ui/format-field-label`, etc. keep resolving unchanged.

Implementation namespaces:
- `wagoe.admin.core.ui.base`           — shared URL/field/column primitives
- `wagoe.admin.core.ui.layout`         — sidebar nav, home, error pages
- `wagoe.admin.core.ui.list`           — entity list page, table, rows, search
- `wagoe.admin.core.ui.filters`        — advanced filter builder
- `wagoe.admin.core.ui.inline-editing` — inline (double-click) cell editing
- `wagoe.admin.core.ui.detail`         — detail/edit page, form, field grouping
- `wagoe.admin.core.ui.drawer`         — the record drawer beside the list

See each impl namespace for the original docstrings on these functions.

Shared admin UI primitives used across multiple ui.* sections.

Leaf namespace: URL helpers, field-value rendering, list-column width
heuristics, and small formatting/label utilities. Must NOT require any
other wagoe.admin.core.ui.* implementation namespace — it is the
dependency root that the focused sections build on.

List cells rendered by display role (ADR-040).

`cell` turns one value into the content of its list cell according to the
field's role; `cell-class` is the class every cell of that role carries, so
the stylesheet styles roles, never fields. What a cell needs beyond the
value — a relation's title, a has-many count, the time — arrives in the
overview the shell computed for the page. Pure Hiccup.

Entity detail/edit page components: form widgets, field grouping, the
entity form, parent-context/related-records tables, and the detail page.

Pure Hiccup generators. Depends on `base` for URL and field helpers.

The record drawer: one record beside its list, opened by clicking its row.

Read-only, rendered by the same display roles as the list cells (ADR-040),
so a relation is a name, an enum a badge, money formatted. Editing stays on
the detail page; the drawer links there. Pure Hiccup.

Advanced filter builder components for admin entity lists.

Pure Hiccup generators for the filter UI: operator selection per field
type, value inputs, filter rows, and the overall filter builder.

Inline (double-click) table-cell editing components.

Pure Hiccup generators for the editable-cell display mode, the inline
edit form, and the inline edit form with a validation error.

Admin nav contribution, page layout, error pages, and URL utilities.

Pure Hiccup generators for the admin chrome: the admin's contribution to
the sidebar of the shell in `wagoe.shared.ui.core.shell`, the dashboard
home, 403/404 error pages and the `build-table-url` helper.

Entity list-page components: search form, table rows, table, and the
complete list page (toolbar + filter builder + table).

Pure Hiccup generators. Depends on `base` for URL helpers, field-value
rendering, and column sizing, and on `filters` for the filter builder.
