fix(ui): invite page goes blank from companies query-key collision (#6433)
## Thinking Path

> - Paperclip orchestrates AI agents for zero-human companies; humans
operate the board through the React UI.
> - The board gates company access via `CompanyProvider`
(CompanyContext) and onboards new humans through the invite landing page
at `/invite/:token`.
> - Reported symptom: opening an invite link and signing in works, but
the page then renders completely blank (black in dark mode).
> - End-to-end browser testing reproduced a client-side crash:
`companiesQuery.data?.some is not a function` and `Cannot read
properties of undefined (reading 'filter')`.
> - Root cause: `CompanyProvider` and `InviteLandingPage` both use the
React Query key `["companies"]` but return **different shapes** — `{
companies, unauthorized }` vs a bare `Company[]` — so they silently
corrupt the shared cache entry; whichever component reads the other's
shape calls `.some()`/`.filter()` on the wrong type and throws,
unmounting the tree.
> - Owners never hit it (they never mount the invite page); only
invitees landing on `/invite/:token` crash.
> - This PR unifies the `["companies"]` query into a single shared
definition so the cache entry always has one shape and the two consumers
can't drift apart again.
> - The benefit is a working invite/onboarding flow and removal of a
whole class of cache-shape bugs on this key.

## What Changed

- Add `ui/src/api/companies-query.ts` exporting a single shared
`companiesListQueryOptions` (and `CompanyListResult`) — one `queryKey` +
one `queryFn` that always returns the wrapped `{ companies, unauthorized
}` shape, documented with the shared-cache contract.
- `ui/src/context/CompanyContext.tsx` now uses
`useQuery(companiesListQueryOptions)` instead of an inline copy of that
query.
- `ui/src/pages/InviteLanding.tsx` uses the same
`companiesListQueryOptions` (with its own `enabled` gate), reads
`companiesQuery.data?.companies` for the membership checks, and uses
`queryClient.fetchQuery(companiesListQueryOptions)` in the post-auth
path — so it reads and writes the identical shape.

## Verification

- `pnpm --filter @paperclipai/ui typecheck` — clean.
- `vitest run src/pages/InviteLanding.test.tsx
src/context/CompanyContext.test.tsx` — 17/17 pass, unchanged.
- Manual end-to-end via a real browser against a LAN-exposed
authenticated instance:
  - Owner creates an Owner-role invite.
- New user opens the link and registers — **the "awaiting approval"
screen renders** (previously blank), `POST /api/invites/:token/accept`
returns `202`, no console errors.
- Owner approves at Company Settings → Access (`200`); invitee becomes
an active member.
- Invitee signs in — full board loads; smoke test of dashboard / issues
/ inbox / routines / goals / company settings — all render, zero
`pageerror`s.
- Before: invite page `#root` empty after sign-in (blank/black). After:
awaiting-approval panel renders. (Screenshots available on request.)

## Risks

- Low. `CompanyProvider`'s query behavior is unchanged (same `queryFn`
logic, just extracted into a shared module). `InviteLandingPage` now
reads the same shape it writes. No API, schema, or migration changes.
Existing tests pass unchanged.

## Model Used

- Claude (Anthropic), model ID `claude-opus-4-7` (Opus 4.7), 1M-context,
extended thinking + tool use; driving Claude Code with browser
automation for end-to-end reproduction and verification.

## Checklist

- [x] I have included a thinking path that traces from project context
to this change
- [x] I have specified the model used (with version and capability
details)
- [x] I have checked ROADMAP.md and confirmed this PR does not duplicate
planned core work
- [x] I have run tests locally and they pass
- [ ] I have added or updated tests where applicable (existing
InviteLanding/CompanyContext tests cover the touched code and pass; a
cross-provider regression test that mounts both consumers is a sensible
follow-up)
- [ ] If this change affects the UI, I have included before/after
screenshots (described textually above; this is a crash/blank-page fix,
screenshots available on request)
- [x] I have considered and documented any risks above
- [x] I will address all Greptile and reviewer comments before
requesting merge
