Merge Gashboard ngit proposal with native access and durable chat

Reviewed proposal acd65f3c (pr/gashboard), exact head 4e167cbcf8. Preserve current catalogs including DATUM and normalize new app memory limit to supported 512m.

Validation: all six focused API security/persistence tests, API TypeScript check and strict release catalog drift pass. No real chat/member changes, miner shares, payout operations, node restart or publication performed by this integration.
