fix(traces): partition trace_facets_hourly by day - #1116

Confidence 4/5 · likely safe to merge
The load-bearing constants are right (bfaed79b…f941 recomputed for v25), and the new local step only drops and rebuilds a 30-day derived rollup from its source MV.

Partitions trace_facets_hourly by day instead of month, so the 30-day TTL no longer outruns the partition period and tinybird deploy accepts the datasource. Adds local store step v24 -> v25 to recreate and rebuild the rollup, and bumps LOCAL_SCHEMA_VERSION to 25. Safe to merge.

• trace_facets_hourly moves to PARTITION BY toDate(Hour)
• Migration 0034's CREATE statements edited in place to match the emitter
• New step local-0024-to-0025-trace-facets-hourly-daily-partition drops and rebuilds the rollup
• LOCAL_SCHEMA_VERSION is 25 with a frozen v25 snapshot and history entry
