chore(ts-migration): migrate components/krow to TypeScript with real prop types

Phase 8, first batch: 56 files, plus three supporting edits outside the folder.
All 56 emit byte-identical JavaScript and the production bundle is byte-identical
to 543da9d.

This batch establishes the pattern for the remaining component work: real prop
interfaces built from actual call sites, reusing the generated entity types.
Fifty-four components now declare what they take -
`CandidateCard({ application: JobApplication, jobTitle?: string, rank: number })`,
`MatchedCandidates({ job: JobPosting, profiles: ProfileView[], ... })` - rather
than carrying a compatibility bag. Callbacks are optional because call sites
omit them; entity props are required because call sites always pass them. Where
a call site proved otherwise, the call site won: `ScheduleInterviewModal`'s
`position`, `CandidateCard`'s `jobTitle`, `TalentDetailModal`'s `matchScore` and
`matchReasons` are optional because real callers omit them.

Two view types absorb what the registry cannot describe. `ProfileView` and
`CourseView` narrow the `jsonb` columns these components read through -
`experience`, `completed_courses`, `earned_badges`, `capabilities`,
`score_breakdown`, `challenge`, `quiz` - to arrays and objects, while every
field backed by a real column keeps the registry's type. They are declared once
for the folder, and their narrowed fields stay REQUIRED: the registry has those
columns NOT NULL, and making them optional broke assignment back to the entity
where `ChallengeRunner` hands a course to a mutation.

TWO REAL DEFECTS FOUND, BOTH PRESERVED RATHER THAN FIXED:

  1. `SuggestedTalent` calls `matchTalent.mutate({...}).then(...)`. React
     Query's `mutate` returns `void`, so that `.then` throws at run time, and
     `runMatch` is reachable from a button. `mutateAsync` is what the code
     means. Swapping it turns a crash into a working feature, which is a
     product change, not a migration one - so it is cast to compile and left
     behaving exactly as it did. This one deserves a fix on its own terms.

  2. `TalentPoolCard` renders a location row behind `profile.location &&`, but
     `worker_profiles` has no `location` column - the registry has none and the
     API cannot send one, so the row has never rendered. Recorded as an
     optional field on `ProfileView` with a note, the same treatment as
     `user.avatar_url` in Phase 7.

Also fixed, all type-only: the Web Speech API declared as the optional `Window`
members `AIInterviewModal` already feature-detects; four `new Promise<void>`
where `resolve()` takes no argument; `toast`'s options bag made optional on
every method, which callers had always omitted; five `krowHooks` query
arguments made optional, which callers had always omitted.

One automated pass was reverted rather than shipped. A local-component
annotator captured words out of the preceding JSDoc as prop names - producing
`interface FrameProps { one?: any; every?: any }` from a sentence about
"one surface, one padding, every step" - the same class of regex error as
Phase 6's. The whole folder was restored from the index and the sound steps
re-run, then local components were annotated with an index-spliced rewrite that
reads only the destructuring.

Verified: tsc 35 -> 22, set-difference showing thirteen removed and none added;
zero errors in any of the 56 files; all 56 emit byte-identical JavaScript;
production bundle byte-identical; npm test 1684/1691 with the same seven
failures; Owliver baseline 59/59; lint 0 errors; baseline artifacts untouched.
