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).

 - Cached source data from before the spell description feature was added: existing cached entries lack the new per-spell data fields. The IndexedDB schema version MUST be bumped to invalidate old caches and trigger re-fetch (re-normalization from raw Foundry data is not possible because the original raw JSON is not retained).
 - Creature with no recognized type trait (e.g., a creature whose only traits are not in the type-to-skill mapping): the Recall Knowledge line is omitted entirely.
 - Creature with a type trait that maps to multiple skills (e.g., Beast → Arcana/Nature): both skills are shown.

 - **Search Index (D&D)** (`BestiaryIndex`): Pre-shipped lightweight dataset keyed by name + source, containing mechanical facts (name, source code, AC, HP average, DEX score, CR, initiative proficiency multiplier, size, type) for all creatures. Sufficient for adding combatants; insufficient for rendering a full stat block.
 - **Search Index (PF2e)** (`Pf2eBestiaryIndex`): Pre-shipped lightweight dataset for PF2e creatures, containing name, source code, AC, HP, level, Perception modifier, size, and creature type. Parallel to the D&D search index but with PF2e-specific fields (level instead of CR, Perception instead of DEX/proficiency).
 - **Source** (`BestiarySource`): A D&D or PF2e publication identified by a code (e.g., "XMM") with a display name (e.g., "Monster Manual (2025)"). Caching and fetching operate at the source level.
-- **Creature (Full)** (`Creature`): A complete creature record with all stat block data (traits, actions, legendary actions, spellcasting, etc.), available only after source data is fetched/uploaded and cached. Identified by a branded `CreatureId`. For PF2e creatures, each spell entry inside `spellcasting` carries full per-spell data (slug, level, traits, range, action cost, target/area, duration, defense, description, heightening) extracted from the embedded `items[type=spell]` data on the source NPC, enabling inline spell description display without additional fetches. PF2e creatures also carry an `equipment` list of carried items (weapons, consumables) extracted from `items[type=weapon]` and `items[type=consumable]` entries, each with name, level, traits, description, and (for scrolls) embedded spell data.
