[codex] Add access cleanup and user profile page (#4088)

## Thinking Path

> - Paperclip is moving from a solo local operator model toward teams
supervising AI-agent companies.
> - Human access management and human-visible profile surfaces are part
of that multiple-user path.
> - The branch included related access cleanup, archived-member removal,
permission protection, and a user profile page.
> - These changes share company membership, user attribution, and
access-service behavior.
> - This pull request groups those human access/profile changes into one
standalone branch.
> - The benefit is safer member removal behavior and a first profile
surface for user work, activity, and cost attribution.

## What Changed

- Added archived company member removal support across shared contracts,
server routes/services, and UI.
- Protected company member removal with stricter permission checks and
tests.
- Added company user profile API, shared types, route wiring, client
API, route, and UI page.
- Simplified the user profile page visual design to a neutral
typography-led layout.

## Verification

- `pnpm install --frozen-lockfile`
- `pnpm exec vitest run server/src/__tests__/access-service.test.ts
server/src/__tests__/user-profile-routes.test.ts
ui/src/pages/CompanyAccess.test.tsx --hookTimeout=30000`
- `pnpm exec vitest run server/src/__tests__/user-profile-routes.test.ts
--testTimeout=30000 --hookTimeout=30000` after an initial local
embedded-Postgres hook timeout in the combined run.
- Split integration check: merged after runtime/governance and
dev-infra/backups with no merge conflicts.
- Confirmed this branch does not include `pnpm-lock.yaml`.

## Risks

- Medium risk: changes member removal permissions and adds a new user
profile route with cross-table stats.
- The profile page is a new UI surface and may need visual follow-up in
browser QA.
- No database migrations are included.

> For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and
discuss it in `#dev` before opening the PR. Feature PRs that overlap
with planned core work may need to be redirected — check the roadmap
first. See `CONTRIBUTING.md`.

## Model Used

- OpenAI Codex, GPT-5.4 tool-enabled coding model, agentic
code-editing/runtime with local shell and GitHub CLI access; exact
context window and reasoning mode are not exposed by the Paperclip
harness.
