R1 cleanup: collAnon and dead code gone, docs current, every peer's scenario in one sweep

Starts the completion program (docs/ROADMAP.md, "Owner decisions on finishing everything", 2026-10-17).

- Dead code: the commented-out collAnon blocks (discussions, seeding, admin user lists, HTTP/3, the old signature
  middleware), the empty PrivaPubWorkersConfiguration, PublicAvatarUsersService and UserPolicyType, unused helpers,
  the second IPasswordHasher registration, the PasswordGenerator package, SignUpAsync/LoginAsync's unused invitation
  parameters. "Starting PrivaPub"; a signed-in login is sent to "/", not to "/discussions".
- Stored fields nothing read: RootUser.Contacts and ResetPasswordToken*, the local Avatar.AvatarServer,
  EmailRecovery.RecoveryCode/RequestIP/CreationDate, MongoSettings.LogsDatabase, and AppConfiguration's
  upload/discussion keys, RequiresFirstTimeSetup and Version (old documents still load: MongoDB.Entities ignores extra
  elements). DmPost's indexes are no longer made. 49 collAnon keys leave FieldsNameResource in every language.
- /clientapi/data/current-version answers the build's ref. UsersIds is a list that can't throw, and the admin routes
  leave the administrator out without mutating the request.
- deploy.yml checks SecureMode on a name no persona can have, and the browser redirect on the directory's first local
  persona: @thepra is the administrator's own now.
- Town: decePub's e2e remnants (expect, client.jsonl, the decePub column) and town/tests go; the dead gaps/load
  commands too. Mobilizon no longer keeps an event for a deleted test.
- tools/pasture/sweep.sh runs every peer's scenario, batch by batch, as CLAUDE.md asks before a change to what
  PrivaPub sends.
- Docs: CLAUDE.md's repo map, route table (every frozen route) and stale lines; ROADMAP's status (setup, v1.25.0,
  v1.26.0, the program C), the 2026-10-17 decisions, and dated notes where earlier text no longer holds; FEDERATION.md's
  FEP list (7888, f228, 7628, ae0c and 8967 supported) and the deploy's persona.

Verified: dotnet build PrivaPub.sln -c Release (0 errors, no new warnings); bash -n on the touched scripts; py_compile
on the town; the pasture's gts, mastodon and lemmy scenarios on this build.
