Andrey Antukh e5f9c1e863 🎉 Add chunked upload API for large media and binary files
Introduce a purpose-agnostic three-step session-based upload API that
allows uploading large binary blobs (media files and .penpot imports)
without hitting multipart size limits.

Backend:
- Migration 0147: new `upload_session` table (profile_id, total_chunks,
  created_at) with indexes on profile_id and created_at.
- Three new RPC commands in media.clj:
    * `create-upload-session`  – allocates a session row; enforces
      `upload-sessions-per-profile` and `upload-chunks-per-session`
      quota limits (configurable in config.clj, defaults 5 / 20).
    * `upload-chunk`           – stores each slice as a storage object;
      validates chunk index bounds and profile ownership.
    * `assemble-file-media-object` – reassembles chunks via the shared
      `assemble-chunks!` helper and creates the final media object.
- `assemble-chunks!` is a public helper in media.clj shared by both
  `assemble-file-media-object` and `import-binfile`.
- `import-binfile` (binfile.clj): accepts an optional `upload-id` param;
  when provided, materialises the temp file from chunks instead of
  expecting an inline multipart body, removing the 200 MiB body limit
  on .penpot imports.  Schema updated with an `:and` validator requiring
  either `:file` or `:upload-id`.
- quotes.clj: new `upload-sessions-per-profile` quota check.
- Background GC task (`tasks/upload_session_gc.clj`): deletes stalled
  (never-completed) sessions older than 1 hour; scheduled daily at
  midnight via the cron system in main.clj.
- backend/AGENTS.md: document the background-task wiring pattern.

Frontend:
- New `app.main.data.uploads` namespace: generic `upload-blob-chunked`
  helper drives steps 1–2 (create session + upload all chunks with a
  concurrency cap of 2) and emits `{:session-id uuid}` for callers.
- `config.cljs`: expose `upload-chunk-size` (default 25 MiB, overridable
  via `penpotUploadChunkSize` global).
- `workspace/media.cljs`: blobs ≥ chunk-size go through the chunked path
  (`upload-blob-chunked` → `assemble-file-media-object`); smaller blobs
  use the existing direct `upload-file-media-object` path.
  `handle-media-error` simplified; `on-error` callback removed.
- `worker/import.cljs`: new `import-blob-via-upload` helper replaces the
  inline multipart approach for both binfile-v1 and binfile-v3 imports.
- `repo.cljs`: `:upload-chunk` derived as a `::multipart-upload`;
  `form-data?` removed from `import-binfile` (JSON params only).

Tests:
- Backend (rpc_media_test.clj): happy path, idempotency, permission
  isolation, invalid media type, missing chunks, session-not-found,
  chunk-index out-of-range, and quota-limit scenarios.
- Frontend (uploads_test.cljs): session creation and chunk-count
  correctness for `upload-blob-chunked`.
- Frontend (workspace_media_test.cljs): direct-upload path for small
  blobs, chunked path for large blobs, and chunk-count correctness for
  `process-blobs`.
- `helpers/http.cljs`: shared fetch-mock helpers (`install-fetch-mock!`,
  `make-json-response`, `make-transit-response`, `url->cmd`).
