Previously the scheduler started searching from the last scheduled post date,
skipping all free slots in between (e.g. a free slot on Apr 20 would be ignored
if the last post was on May 18).
Now starts scanning from tomorrow, finding the first available slot regardless
of whether earlier dates have gaps — fills the calendar naturally.
Also extended lookahead from 30 to 60 days.

The scheduler previously only checked the local SQLite DB for occupied slots.
Posts created outside the pipeline (e.g. recovery scripts) were invisible,
causing newly scheduled articles to land on already-taken WP dates.
_fetch_wp_occupied_slots() now queries WP /wp/v2/posts?status=future before
each slot assignment. All scheduling functions accept a wp_occupied set.
