[Client/Server/Protocol] Surface live metrics in the Developer tab

Extend Response_GetServerStats with live counters from the in-process
MetricsRegistry: cards in games, event loop stall totals/worst,
total commands processed, average command time, active command types,
and game-start count/duration. Add a repeated CommandStats message
carrying per-command breakdowns (kind, extension number, resolved
protobuf name, count, total ms) for every type that has seen at
least one sample.

Server-side cmdGetServerStats() populates all new fields after the
existing DB uptime snapshot query, resolving protobuf extension names
via the descriptor pool for human-readable labels like
session/Command_Ping.

Expand TabDeveloper with two tables: an overview section (existing
DB stats plus the new live metrics) and a per-command breakdown table
(Command / Count / Total ms / Avg ms) sorted by total_ms descending
so the hottest commands surface first.
