feat: improve config import with result tracking and idempotent repository detection

- Add ImportResult type to track succeeded/warnings/errors counts across all import functions
- Implement multi-layer repository duplicate detection:
  - URL-based check (same path/bucket/endpoint already registered)
  - Restic repo check (path is already a restic repository)
  - Name-based fallback check
- Standardize logging between CLI and env var import methods with logImportSummary()
- CLI exits with code 1 when import has errors
- Remove shortId override for local repo migrations (use full path with isExistingRepository instead)
- Update example JSON and README:
  - Document that local repo path is optional (defaults to /var/lib/zerobyte/repositories)
  - Add existing-local-repo example with isExistingRepository: true
  - Add S3 endpoint field to example
  - Expand config behavior docs to explain all repository skip conditions
- Improve .gitignore to exclude all JSON except example template
