fix: add fetch_coins.py to auto-deploy loop + legacy migration comment

- auto-deploy.sh: fetch_coins.py was missing from the root-level .py deploy
  loop (line 72). Only manual deploy.sh had it. Next cycle syncs it to VPS.
- fetch_coins.py: document the ALTER TABLE loop as legacy migration for older
  DBs that predate the CREATE TABLE columns.
