Fix max_persons extraction: read from span text not block_id segment 2

Browse source 
Old Stocks block_id has 0 in position 2 (not the persons count) so all
its rates were stored as max_persons=0 and deprioritised in the matrix.

Now reads max_persons from the visible 'Max persons: N' span (matching
the original scrapy spider), with aria-label/title fallback. block_id
segment 2 is unreliable across different hotel layouts.

Also treat max_persons=0 as unknown in the matrix ORDER BY priority.
