Closes the last gap from tonight's backup-hardening: backup_runs.
statistics now carries a `per_path` map keyed by backup_paths.path
(e.g. `events/active`, `business-docs`), with per-bucket count + size.
Backend (backupService.js):
- new `computePerPathStats(backedUpFiles, allFiles)` helper that
bucket-sorts each backed-up file into its owning backup_paths row
by longest-prefix match. Reuses the same backup_paths source the
walker reads, so toggling include_in_default off propagates
correctly. Falls back to LEGACY_BACKUP_PATHS if the table is
missing.
- runBackupInternal calls it after the destination implementation
reports back, includes the result in statistics under both
snake_case (`per_path`) and camelCase (`perPath`) keys for the
same alias treatment the existing fields get.
Frontend (BackupHistory.jsx):
- Backup History detail pane now renders one row per per_path entry
when present, with path label + count + formatted size.
- Falls back to the legacy Photos / Archives / "Other" rendering
when the field is absent (backups taken before this commit). No
breaking change for stored history.
Tests: new backupService.perPathStats.test.js — 2 scenarios pinning
attribution behaviour (single-path, nested-paths-don't-collide).
Plus a NOTE comment about overlapping-path walker behaviour (out of
scope; canonical seed doesn't hit it).
