The loan-aware NAV fix (0.2.47) only affects new imports; an already-signed
quarter keeps its old holdings until re-imported. Add a boot-time queue: an
operator stages an eNAV plus a small JSON descriptor under
data/pending_reimports and the app re-imports it on startup via the same code
path as the admin Import screen, then removes the processed files. Guarded so a
queue problem never blocks boot. Bumps the package to 0.2.48.
Used to refresh SATS Credit Fund LP Q4 2025 to its full NAV including the
Fold Holdings loan.
