fix: prevent folder-monitor reuploads after completion

Discover base, daily, session, and fallback upload logs across configured, Desktop, and application-data locations without blocking the Electron main process.

Treat in-session completion keys as authoritative automation evidence so removing finished rows cannot cause periodic reconciliation to enqueue and upload the same file again.

Add real handler and done-remove-reconcile regressions covering custom extensions, mixed-case log names, fallback paths, stale evidence, and asynchronous log reads.
