Replace per-row Team/Player lookups with bulk IN-list queries before
the validation loop in post_transactions, post_results, post_schedules,
and post_batstats. A 50-move batch now uses 2 queries instead of 150.

aiohttp follows 307 redirects but converts POST to GET, silently
dropping the request body. Standardize all @router.post('') to
@router.post('/') so the canonical URL always has a trailing slash,
preventing 307 redirects when clients POST with trailing slashes.

The team_abbrev filter uppercased input but compared against mixed-case
DB values (e.g. "MKEMiL"), causing affiliate roster transactions to be
silently dropped from results. Use fn.UPPER() on the DB column to match.
