New api/logretention package: GET /logs/retention/preview and DELETE /logs/retention, both gated to RoleAdmin (Owner satisfies it too), issue purpose-built parameterized statements against ClickHouse's logs table (a count and a synchronous ALTER TABLE ... DELETE mutation) rather than routing through querylang/executor's SELECT-only SQLRunner. Settings gets a new "Log retention" section, visible only to an owner or admin, that previews how many records a chosen age cutoff would remove before showing an explicit confirm/cancel panel -- no delete happens without that second step. Scoped to core's single-tenant ClickHouse table; enterprise/'s per-tenant routing and Tantivy's lack of a bulk-delete primitive are disclosed gaps in api/logretention/store.go's doc comment, not silently assumed to already work.
