Log Message:

Add exponential backoff for dead syndicated feeds

Dead feeds (HTTP errors, DNS failures, parse errors) were polled every 1-3 hours forever with no escalation. Add a failcount column to the syndicated table and apply exponential backoff: base_delay * 2^min(failcount, 7), capped at 30 days. Dead feeds settle into ~monthly polling instead of ~2,920 wasted requests per year.

Three backoff modes: escalate (feed/account errors), reset (success or not-modified), hold (our infrastructure issues like nodb/posterror). Reset failcount on URL change (syn_edit), feed merge, and REST ping.

Also converts SynSuck verbose print statements to Log::Log4perl, removes the now-drained legacy synsuck.pl maint worker, and fixes an out-of-scope $user reference in parse_items_from_feed().
