Codebase cleanup: remove dead code, fix docker, update docs

app.py:
- Remove 'raw' field from export dict entries (only comment/blank
  kinds need raw; export entries are always reconstructed from
  path/rest/enabled when writing back)
- Remove extra blank line

shares.js:
- Remove unused pathJson variable in SMB row (was only needed for
  the quota button, which was removed)

docker-compose.yml:
- Deleted entirely: was missing templates/ and static/ mounts so the
  Flask app couldn't serve pages; SYS_ADMIN cap_add was only needed
  for quotas; deployment is systemd, not Docker

README.md:
- Remove quota package from apt install command
- Remove quota setup section (feature removed)
- Remove docker-compose from Dev section

CLAUDE.md / PLANNING.md:
- Remove docker-compose.yml references and quotas.js from file tree

.gitignore:
- Remove redundant micronas.env entry (already covered by *.env)
