Drop auth.server.ts re-exports + rename to .server.ts convention (task 5.2)
Two cleanups in one pass:

1. Update import paths app-wide from `~/lib/auth.server` to
   `~/lib/auth/session.server` for the four session helpers
   (sessionStorage, createSession, getSessionUser, destroySession).
   ~40 files: 33 simple path swaps where the file imported only session
   symbols, 5 splits where it also imported per-method auth functions
   (auth.verify.tsx, api.settings.email.ts, activities.\$id.tsx,
   routes.\$id.tsx, auth.accept-terms.tsx) — those keep one import
   from auth.server (for verifyMagicToken, canView, recordTermsAcceptance,
   etc.) and gain a second import from auth/session.server.
   Two more files used relative paths and were missed by the first
   grep pass (lib/oauth.server.ts and routes/oauth.authorize.tsx) —
   migrated too.
   The @deprecated re-exports block in auth.server.ts is gone.

2. Rename the new auth files to follow the project's `.server.ts`
   convention so Vite/React Router treat them as server-only (they
   read process.env.SESSION_SECRET, hit the DB, etc. — must NOT enter
   the client bundle):
   - auth/session.ts → auth/session.server.ts
   - auth/completion.ts → auth/completion.server.ts
   - auth/completion.test.ts → auth/completion.server.test.ts
   Done with `git mv` so blame is preserved.

Verified: typecheck + lint green; 126 unit tests pass.
