The previous backfill grouped by (name, address) only, which collapsed
Tractor Supply in Brighton, CO and Tractor Supply in Canon City, CO
into a single location whenever they shared the same address (or both
had a NULL address). Same problem for Ace Hardware, Murdoch's,
Big Tool Box, and JAX Farm & Ranch.
This migration re-dedupes by (name, city, address), re-links all 269
Tuxedo stops to the new per-city venues, and soft-deletes the 26
over-grouped original locations.
Result: 41 active locations (was 26). 269/269 stops re-linked.
Slug regex also fixed — previous [a-z0-9] stripped uppercase letters;
now uses [[:alnum:]].
