Avito leaks addresses with house number glued to district marker without
separator («…Савкова, 29р-н Академический»), breaking house-number extraction
and same-house matching (41 unmatched avito listings on one street).
_clean_address now inserts ", " between a house-number token (digits +
optional Cyrillic letter + optional /N|сN|кN|корпус|стр) and a following
marker (р-н, мкр, район, г., пос, снт, …).
- avito.py: idempotent _deglue_house_marker step (CSS/tail-strip kept)
- tests: de-glue positive/negative/idempotency (24 passed)
- data/sql/124_deglue_avito_addresses.sql: idempotent backfill for stored rows
normalize.py НЕ тронут (общий fingerprint матчинга, #1534).
Закрывает avito-часть #1773 (cian-без-номера + дедуп — отдельно, зона cian).
