Campaign managers often create the campaign in DAM before assets are
uploaded, so an empty Master Assets folder is the normal pre-asset state
rather than a failure. Stop marking these as permanently failed and stop
emailing on every poll.
- increment_a1_retry() gains mark_failed_at_max param; empty-folder path
passes False so the campaign keeps polling indefinitely until assets
appear (or the DAM status changes).
- Empty-folder branch now skips silently on every poll and sends a single
warning email at poll 20 (~1 hour at the 3-min cadence) so genuinely
stuck campaigns still surface.
- New a1_to_a2_no_assets_warning email template — one-time soft warning,
no permanent-failure language.
- Existing reset_a1_retry() on successful A1→A2 still clears the counter
when assets eventually appear.
- Other folder-error paths (folder not found, etc.) keep the original
3-retry-then-fail behavior.
