refactor(e10): move the platform components into components/ui/ and enforce the boundary

The app HAS a platform layer -- AnchoredPopover (22 importers, with
arrows/typeahead/Escape/anchor-flip), QueryState (21), Modal (17),
PageShell, DataTable, Tabs, Tooltip and ~26 more -- but it sat flat among
~160 feature components with nothing marking it as one. Several of those
files describe themselves as 'the one place' or 'canonical' and were
still bypassed by hand-rolled markup, because a layer nobody can see is a
layer nobody uses; three separate inventory passes of this codebase
misread it the same way.

Moves the 33 domain-free modules into components/ui/, rewrites the
imports in 89 files, and makes the boundary a lint rule rather than a
convention: inside ui/ a one-level-up import (a feature component) and
any lib/api slice are errors. The rule was verified to fire on both and
to leave generic lib/ helpers alone. README.md states which side of the
line a component belongs on and why.

No behaviour change: 3x tsc, eslint, knip, prettier and 687 vitest tests
all green; no backend file touched.

// The column-header machinery — the column contract, the sortable header row with its filter
// funnel + popover, and the filter predicate — lifted OUT of DataTable so a non-DataTable body can
// render under the same headers.
//
// Why it lives here and not in DataTable: DataTable owns its filter/sort/page state internally,
// while the playlist manager's body is a drag-reorderable list whose order is the persisted
// server-side one. Two owners of the same ordering fight; composing these pieces instead lets the
// playlist keep its stored order and still get real column headers. Same move as E4 S3's
// ChannelLayoutGrid, which builds a card view straight from the `Column<T>` render closures.

// NEW component type on every render: React unmounted and remounted the popover on each keystroke,
// so the caret jumped to the end and IME composition (accents, any CJK input) broke mid-word. The
// `autoFocus` masked it well enough that it read as "the filter is just twitchy".
//
// The funnel and its panel live in ONE component because the R8 popover platform anchors the panel
// to its trigger. That also retires this file's three hand-rolled focus chores: capturing the
// trigger element at open time (a `ref` scoped to the open column nulled out before focus could go
// back), the restore-focus effect that stopped Escape stranding focus on <body>, and the useDismiss
// registration that had to include the trigger so its own mousedown didn't close-then-reopen.

/** The sticky `<thead>`: one sortable/filterable cell per column.
*
* Sticky-header notes (kept from DataTable, where this look was designed): the header stays put at
* the top of the page scroller while rows scroll under it. `bg-bg` on each cell stops rows showing
* through; the bottom border rides a `box-shadow` because a sticky `<tr>`'s own border scrolls away
* with the collapsed table box in some browsers. The `::after` paints a short fade just BELOW the
* header so rows dissolve as they slide under it while the header itself stays crisp — which is why
* pages using this pass `PageShell fadeTop={false}`. */
