Rename project from llm-proxy to proxy

[joseconstela]

Summary

The repository moved to lab34-es/proxy, so this brings every reference in line with the new name — docs, Docker files, Go module, config defaults, and UI strings (31 files).

• Go module: github.com/lab34/llm-proxy → github.com/lab34-es/proxy (now matching the actual repository host path), with all internal imports updated
• Docker: binary, install path, and ENTRYPOINT renamed to proxy; default DSN is now /data/proxy.db
• docker-compose: service and volume renamed; the image now points at ghcr.io/lab34-es/proxy:latest — fixing a pre-existing bug, since the publish workflow pushes to ghcr.io/${{ github.repository }} and the old ghcr.io/lab34/llm-proxy reference was never published
• Docs & UI: README title, build commands and project tree; OpenAPI title and Swagger page title now read lab34/proxy, matching the console branding; dashboard footer reads "lab34 — proxy"; startup log prints proxy listening on :8080
• .gitignore: entries renamed and root-anchored (/proxy, /proxy.db, …) — an unanchored proxy entry would have silently ignored new files under the internal/proxy/ package
• coverage.out: regenerated by running the suite under the new module path

Deliberately unchanged

• The llmp- API key prefix: it is a wire format, and renaming it would invalidate every already-issued key
• Descriptive prose like "An OpenAI-compatible LLM proxy that routes…" — it describes what the software does, not its name
• CI workflows — they already use ${{ github.repository }}

Test plan

• Full Go test suite passes under the new module path (go test ./internal/...), coverage 83.8% — above the 80% CI gate
• go vet clean; release binary builds (go build -trimpath -ldflags="-s -w" -o proxy .)
• Frontend production build succeeds (npm ci && npm run build)
• git check-ignore verified: root proxy binary ignored, internal/proxy/ package not ignored
• Repo-wide sweep confirms no remaining name references (only descriptive "LLM proxy" prose and the intentional llmp- prefix remain)
