Add PF2e attack effects, ability frequency, and perception details

Show inline on-hit effects on attack lines (e.g., "plus Grab"), frequency
limits on abilities (e.g., "(1/day)"), and perception details text alongside
senses. Strip redundant frequency lines from Foundry descriptions.

Also add resilient PF2e source fetching: batched requests with retry,
graceful handling of ad-blocker-blocked creature files (partial success
with toast warning and re-fetch prompt for missing creatures).
