feat(web-app-peertube): add dynamic performance tuning for heap and transcoding concurrency

- Dynamically calculate PEERTUBE_MAX_OLD_SPACE_SIZE (~35% of container RAM, clamped between 768–3072 MB)
- Dynamically calculate PEERTUBE_TRANSCODING_CONCURRENCY (~½ vCPUs, min 1, max 8)
- Added default resource limits for Redis and Peertube containers
- Updated test suite to include human_to_bytes filter in built-in filter list
