sgaofen 93ea9b04af fix(gateway): cap inbound media download size to prevent memory exhaustion
Inbound image/audio/video payloads were buffered fully into process memory
before being written to the cache, with no size limit. A large upload
(Discord Nitro allows 500 MB) or a remote media URL in an inbound message
pointing at a huge file could spike RAM and OOM-kill the gateway.

Enforce a configurable cap in the shared cache helpers (gateway/platforms/
base.py) so the protection holds across every platform adapter, not one:

- cache_image/audio/video_from_bytes reject oversized payloads before writing
  (video was the gap in the original report — now covered).
- cache_image/audio_from_url stream the body, rejecting on an oversized
  Content-Length header and re-checking the running total per chunk so an
  absent/lying header can't smuggle an unbounded body past the cap.
- Discord's _read_attachment_bytes checks att.size up front, so an oversized
  attachment is rejected before any bytes are pulled into memory.

Configurable via gateway.max_inbound_media_bytes in config.yaml (default
128 MiB; 0 disables). No new env var — non-secret config lives in config.yaml.

Salvaged and extended from @sgaofen's PR #13341 (the original report and the
shared-helper approach). Reapplied onto current main (Discord adapter has
since moved to plugins/platforms/discord/), the configurable knob moved from
an env var to config.yaml, and the video cache helper added.
