Merge pull request 'fix: invalidate stale predicted_rating after PDGA cycle rollover (#29)' (#31) from fix/invalidate-stale-predicted-rating-29 into main

Reviewer 1 flagged: staleness-check read predicted_calculated_at from
the original cachedPlayer snapshot even after recompute, so newly
calculated ratings (predicted_calculated_at = NULL in snapshot)
were immediately nulled by the staleness branch.

Fix: read predicted_calculated_at from updatedPlayer too.

Reviewer 2 nit: rename thisMonths → secondTuesday for consistency
with the original variable name in getNextPDGAUpdateDate.
