C1: bump shower to v1.0.2 (WhiteNoise upstreamed); cache static on fly

App v1.0.2 ships WhiteNoise for /static/ and /media/, so the
blumeops-side workaround is no longer needed:

  - containers/shower/default.nix: drop the WhiteNoise pip dep + the
    middleware-injection block from local_settings. The shim is back
    to just path overrides (DATABASES.NAME, MEDIA_ROOT, STATIC_ROOT).
  - version → 1.0.2, outputHash → fakeHash for re-pinning.
  - service-versions.yaml mirrored.

fly/nginx.conf: cache /static/ (1y) and /media/ (1d) per location for
shower.eblu.me. /static/ filenames are content-hashed thanks to
CompressedManifestStaticFilesStorage so a year is safe and invalidation
is automatic on the next collectstatic.
