fix: persist GlitchTip GzipChunk patch and prune old releases in CI

- Add homelab/glitchtip/files_api.py with GzipChunk fallback for sentry-cli 3.x
  raw zip uploads; bind-mount into both glitchtip-web and glitchtip-worker
- Add release.yaml prune step to delete all but the 10 newest GlitchTip releases
- Reader page: remove dead code and simplify layout
