MCP stats: implement in-memory show_queries Top-K path

Replace stats table reads in show_queries with Query Processor in-memory aggregation to avoid stale/empty admin-db snapshots.\n\nIntroduce Top-K digest filtering primitives and wire them into Stats_Tool_Handler so filtering/sorting/limit are executed against live digest memory.

Add runtime MCP variable mcp-stats_show_queries_max_rows with validation, defaulting, and configuration plumbing, plus cap metadata in the tool response.\n\nEnforce configurable hard cap semantics while preserving deterministic ordering and pagination behavior for MCP clients.

Add internal DEBUG validator path (PROXYSQLTEST 56) in admin tests to stress generated digest data and validate the Top-K/filter pipeline against in-memory state.\n\nKeep the validator callable from startup/testing workflows without depending on MCP linkage.

Add TAP coverage in test/tap/tests/mcp_show_queries_topk-t.cpp for:\n- MCP endpoint setup and reachability\n- digest generation + optional DEBUG internal validator\n- payload validation and cap metadata assertions\n- descending count order validation\n- match_digest_text filter verification\n\nMake payload parsing backward-compatible in TAP (direct tool result object and legacy wrapped success/result payloads).
