feat: Phase 6 export — writes Grav entry folders from Immich originals

Implements GET /export summary view and POST /export/run which downloads
originals from Immich, writes entry.md with YAML frontmatter, and sets
group status to exported. Includes POST /export/overwrite for single-group
re-export. All 42 tests pass.
