* feat(mcp-oauth): let an account with no company connect and sign up from the OAuth popup

Identity unlock for agent-first onboarding (#1814, shape B+). A person
with no Accounted account can now connect from an MCP client, create the
account inside the Connect popup and finish the OAuth dance.

- authorize/token no longer require a company: consent renders a
  companyless variant and the key is minted with company_id NULL.
- validateApiKey returns companyId string|null and binds an unbound key
  to the user's first company on the first validation after it exists.
- MCP server: company-dependent tools and data resources answer with a
  structured NO_COMPANY_YET error; the company-independent tools still
  run; telemetry skips when there is no company scope.
- /api/events fails closed instead of throwing for an unbound key.
- authorize forces TOTP enrollment (not just verification) for password
  accounts with no factor, since the middleware skips enrollment for
  zero-company users; BankID-linked accounts stay exempt.
- /login forwards next to /register; register, GoogleAuthButton and
  /auth/callback carry it back to the consent page (callback honours
  only /api/mcp-oauth/authorize, via safeReturnTo); /mfa/enroll
  hard-navigates to /api/* destinations like /mfa/verify.

* refactor(company): move getActiveCompanyId out of the next/headers module

lib/auth/api-keys.ts needs the resolver for unbound-key binding, but
lib/company/context.ts imports next/headers for the legacy company cookie
and Turbopack refuses that import on some of api-keys' import paths (the
preview build failed). The resolver and CompanyContextError now live in
lib/company/active-company.ts; context.ts re-exports them so every caller
and test mock is unchanged.

* fix(mcp-oauth): fail closed on a failed assurance lookup; enroll Back aborts instead of looping

Review findings on #1855: requireAal2 let consent through at AAL1 when
getAuthenticatorAssuranceLevel() returned nothing and a verified factor
existed. Only a positive AAL2 answer passes now; a failed lookup and the
inconsistent verified-factor-at-AAL1 case both step up to /mfa/verify.
Back on /mfa/enroll with the consent page as returnTo went straight back
into the redirect loop; it now aborts to the app.
