feat: add persistence/HA system constants to config.h with tests (P0-A)

Browse source 
Adds 17 compile-time constants covering WAL format, HA topology,
snapshot sizing, and operational defaults. test_persistence_constants
in test_config.c validates every constant value; all 6 config tests
pass (4 pre-existing unrelated failures unchanged).
