fix: truncate timestamps to date in Daily_Record_Ct measure formula

COUNT(DISTINCT col) on timestamp columns counts unique timestamps, not
unique dates, producing negative measures (e.g., -1575 instead of 240).
Add CAST(col AS DATE) for 7 flavors that were missing date truncation:
postgresql, snowflake, databricks, redshift, redshift_spectrum, mssql, trino.
BigQuery, Oracle, and SAP HANA already truncated correctly.
