feat(web/ui): migrate IntakeUrlBar input to common Input primitive

The IntakeUrlBar URL field was a raw <input> with ~10 lines of inline
styling carrying its own border/radius/background/font-size. This was
the last component on the dashboard surface still using a raw input
after UI5\u2013UI7, so the ratchet caught it as remaining drift.

Migrated:
  - Raw <input> + inline style block \u2192 common <Input> primitive.
  - Preserved the absolute-positioned content-type badge overlay by
    keeping the wrapper <div style={{ position: 'relative' }}> and
    using Input's style prop to right-pad when a badge is present.
  - All attributes (type=url, value, onChange, onKeyDown, placeholder,
    aria-label) preserved as-is so no behavioral change.

Ratchet impact:
  raw interactive controls: 14 \u2192 13 (\u20131)

Lowered scripts/ui-drift-baseline.json from 14 to 13 with this commit
so the CI gate now enforces that bound. The remaining 13 raw controls
are intentional and tracked:
  - NoteEditor toolbar buttons (9)  \u2014 icon-tight, deliberately raw
  - ArtifactPanel hidden file input (1) \u2014 must remain <input hidden>
  - Search-mode radios (2) \u2014 would change UX to migrate to Radix RadioGroup
  - NoteVersionsPanel disclosure button (1) \u2014 tight inline styling

Verified:
  - pnpm --filter @notelett/web run typecheck \u2014 ok
  - pnpm --filter @notelett/web run test \u2014 96/96 pass
  - bash scripts/ui-drift-ratchet.sh \u2014 all categories at new baseline
