fix(aym,uyusmazlik): adapt to rebuilt AYM and Uyuşmazlık sites

Both sites were rebuilt and their old endpoints now 404:
- AYM moved to a single-page app backed by a JSON API
  (POST /api/core/public/search, kararTipi NormDenetimi/BireyselBasvuru;
  full text via {id, size:1} -> "icerik" HTML). Old /Ara, /ND/, /BB/ gone.
- Uyuşmazlık moved to ASP.NET WebForms (viewstate postback to /, GridView
  results, decisions served as /Uploads/{EsasNo}.pdf). Old /Arama/Search gone.

Changes:
- New anayasa_mcp_module/api_client.py: shared KBB JSON client, base64url
  document-id codec, HTML->Markdown + HTML text stripping helpers.
- Rewrite anayasa client/bireysel_client/unified_client over the new API,
  preserving public method names and response models.
- Rewrite uyusmazlik client for the postback flow + GridView parse + PDF
  document conversion; simplify request model to text + scope + paging.
- Trim search_anayasa_unified and search_uyusmazlik_decisions tool signatures
  to parameters the new APIs actually support; drop dead enums.

Verified live via FastMCP client: search + document retrieval work for AYM
norm/bireysel and Uyuşmazlık.
