[Server/Client/Protocol] Add developer staff role

Introduce a Developer staff level (proto flag 32, DB admin bit 8) that
sits between admin and moderator: no kick/ban/warn/report/admin powers,
but gets server log access via a new developer command container family
(GET_SERVER_STATS, VIEWLOG_HISTORY) and an idle-timeout exemption.

- Protocol: IsDeveloper flag, developer_commands.proto envelope,
  Command_GetServerStats/Command_GetLogHistory, Response_GetServerStats,
  Command_AdjustMod.should_be_developer
- Servatrice: fail-closed developer dispatcher, uptime snapshot handler,
  shared log history handler reuse, bit-8 DB mapping
- Client: burgundy pawn/badge/labels/sort order, prepareDeveloperCommand,
  minimal Developer stats tab, log tab access, promote/demote actions
