Add AKC mirror site

[Sun-sunshine06]

Summary

• Adds an American Kennel Club mirror under sites/akc with breed browsing, breed selector, compare, advice, events, login/profile, saved breeds, and event registration flows.
• Registers akc as the next site on the upstream 15-site base, exposed on port 40015.
• Adds Docker build-time seed generation for the code-generated SQLite seed DB.

Verification

• sites/akc/venv/Scripts/python.exe -m py_compile sites/akc/app.py
• python -m py_compile control_server.py
• tasks.jsonl JSON parse check passed
• Flask test client smoke: /, /breeds, /breeds/labrador-retriever, /breed-selector, /compare, /articles, /events, /search?q=agility, /login all returned 200
• Login as alice.j@test.com and event registration flow returned 200

Note

• This branch is rebased onto aiming-lab/WebHarbor main and does not include hqhq1025 fork-only site changes.

Reviewer checklist (WebHarbor Review Guide)

Reviewer note: Source-level review (checked out pull/40/head). The mechanical Docker pipeline (build, curl 200, md5 reset) was not run in my environment — please pair with a Docker-capable mechanical pass.

Visual fidelity: ❌ FAIL

• The most built-out of this contributor's set (app ~522 lines; breed_detail/compare/selector/events/articles; branded AKC header). But breed imagery is the /breed-art/<slug>.svg placeholder — real AKC pages are defined by distinctive breed photography, so this fails the real-images check.

Functional depth: ✅ PASS

• Breed browse with group/size filters, breed detail, breed selector with real scoring logic (energy/grooming/apartment matching), compare, expert-advice articles, events with registration, login/register, save-breed, owner-profile update. Trait ratings (energy/grooming 1–5) mirror AKC's real trait scales.

Task quality: ⚠️ Request changes (10 tasks)

• Good: AKC--1 (breed selector: apartment + moderate energy + low grooming → recommend), --2 (compare Golden Retriever vs Border Collie energy — decided on the compare page, not leaked), --5 (filter events to Training → CGC test city/state), --8 (register a dog for a webinar = real state change).
• Only 10 tasks (need 15–20); AKC--3 leaks the password; confirm group/temperament answers require the detail page, not the card.

Verdict: Request changes

(1) Use real breed photos; (2) provide 15–20 tasks with more ≥5-step reasoning; (3) remove the credential leak; (4) verify card-vs-detail answer placement. Best functional depth of the contributor's set.
