perf: bound archive filter inventory queries

[chubes4]

Summary

• replace eligible per-taxonomy unbounded event-ID materialization with selective grouped assignment counts
• reuse grouped rows by Calendar generation while rerunning query-mutation eligibility before every cache hit
• preserve canonical WP_Query/wp_get_object_terms fallback for customized, portable, scoped, and failed query paths
• add production-shaped hierarchy, cross-filter, temporal, cache, hook, SQL-failure, and portability coverage

Production Context

After #749/#753, the USA-root date aggregate improved from 2.509s to 0.643s, but /location/usa?past=1 remained 7.336s cold and 5.626s immediately repeated. The remaining archive-render path called FilterAbilities once per public taxonomy, materializing the complete matching ID set before tallying each taxonomy.

Why This Does Not Repeat #736

The reverted #736 query was additive and joined the broad canonical posts query, adding a 1.384s / 1,097,796-row grouped scan while old scans remained. This change replaces eligible scans and starts from the one-row-per-event date table. Taxonomy constraints use indexed EXISTS; counted assignments group directly with COUNT(DISTINCT ed.post_id).

Safety

• hierarchical terms expand through the existing canonical term-taxonomy resolver
• direct, child, deep, and multi-term assignments deduplicate exactly
• active cross-filters exclude the currently counted taxonomy as before
• query mutation detection executes before cache lookup, so warmed rows cannot bypass request constraints
• term/query callbacks, short circuits, SQLite/non-MySQL, search, geo, scope tokens, and SQL errors use canonical fallback
• only normalized aggregate rows are cached; request-sensitive term objects and exclusion output are rebuilt

Verification

• PHP syntax: pass for all changed files
• git diff --check: pass
• changed-file PHPCS: pass
• changed-file PHPStan level 7: pass
• independent blocker review: no release-blocking findings
• local WordPress PHPUnit unavailable because WP Codebox returned an unparseable recipe payload; hosted MySQL/multisite CI is authoritative

Closes #735
