Remove legacy TheSchwartz ESN workers and ESN_OVER_SQS tunable (#3520)

• Remove legacy TheSchwartz ESN workers and ESN_OVER_SQS tunable

$LJ::ESN_OVER_SQS has been 1 in production, meaning 100% of ESN events route through DW::TaskQueue (SQS). The four legacy TheSchwartz-based ESN workers are consuming no work. This removes the legacy path entirely so ESN always uses the modern DW::Task::ESN::* pipeline.

• DW::TaskQueue dispatch() now unconditionally calls fire_task for events
• LJ::Event::fire_job() removed; process_fired_events() rewritten to drain DW::TaskQueue synchronously (used by tests)
• LJ::ESN: removed schwartz_capabilities(), process_fired_events(), jobs_of_unique_matching_subs(), and all four LJ::Worker::* packages
• Deleted 10 legacy worker scripts from bin/worker/
• Removed esn-legacy entries from workers.json and dwtool CategoryOrder
• LocalDisk::receive() gains optional wait_secs param (default 10) so process_fired_events can do non-blocking receives

• Remove dead schwartz_role methods from LJ::Event

schwartz_role was used by the legacy TheSchwartz ESN workers (removed in the previous commit) to route certain event types to the mass job database. No code calls these methods anymore.

• Remove sch_mass_* table DDL from update-db-general.pl

These TheSchwartz tables were used by the mass ESN workers to process high-volume events on a separate job database. No code reads from or writes to them anymore — all ESN goes through DW::TaskQueue/SQS. The tables will remain in existing databases until manually dropped.
