fix(extract,transform): fix COT/prices column name mismatches + OWM rate limit skip

- fct_cot_positioning: quote Swap__Positions_Short_All and Swap__Positions_Spread_All
  (CSV uses double underscore; DuckDB preserves header names exactly)
- fct_cot_positioning: quote Report_Date_as_YYYY-MM-DD (dashes preserved in header)
- fct_coffee_prices: quote "Adj Close" (space in CSV header)
- openmeteo/execute.py: skip API call in backfill when all daily files already exist
  (_count_existing_files pre-check prevents 429 rate limit on re-runs)
- dev_run.sh: open browser as admin@beanflows.coffee instead of pro@
