fix(web): clean up API docs — parameterized /tile path, truthful examples, image-query one-liner

[andylizf]

What

• /tile endpoint listing: show the parameterized path /tile/{article_id}/{tile_index}/{chunk_index} in the sidebar/endpoint list instead of a hardcoded concrete ID, and move it up next to /search (it's step 2 of the search flow; /status and /health go after).
• Fix wrong example IDs: the docs claimed tile 2840114/0/0 is the top of the Albert Einstein article — it's actually Fresno_State–Hawaii_football_rivalry. Einstein is 698618/0/0 (verified by fetching the tile). The quickstart's photosynthesis example now shows the real top hit (5878188/1/0, the Photosynthesis article — verified live).
• Image-query example: add a copy-pasteable one-liner that base64-encodes a local file inline and POSTs it:

  curl -X POST https://pixelrag.ai/api/search \
    -H "Content-Type: application/json" \
    -d "{\"queries\": [{\"image\": \"$(base64 < photo.jpg | tr -d '\n')\"}], \"n_docs\": 5}"

  (base64 < file | tr -d '\n' is portable across Linux and macOS.)

Verification

• tsc --noEmit passes.
• The image-query example was executed verbatim as rendered against the live API; querying with a thumbnail of a tile returns the tile's source article among the top hits.
• Both new example tiles (698618/0/0 Einstein, 5878188/1/0 Photosynthesis) fetched and visually confirmed.
