Harden secrets handling: env-var DB password + defensive .gitignore

Move hardcoded 'rootpassword' default in parser/{config,backfill_changeover,
clmparser,udcparser}.py behind os.environ.get('SHOPDB_DB_PASSWORD',
'rootpassword'). Add defensive patterns (.env, *.key, *.pem, id_rsa*,
secrets.*, etc.) to .gitignore across all project repos.
