The PROGMEM_STRING_TABLE expansion is entirely constexpr-initialized, so it doesn't require the per-static thread-safe-init guard variables that the previous `static const LogString *const FIELD_NAMES[8] PROGMEM = { LOG_STR(...) }` form emitted inside validate_() (LOG_STR contains a GCC statement-expression, which is not a constant expression, so GCC fell back to dynamic init with an 8-byte guard).
Combined the 8 clamp-field names and "Color temperature" into a single ValidateFieldNames table; index 8 is reserved for CT. log_value_out_of_range_() now takes the resolved `const LogString *` directly, so the helper no longer needs its internal progmem_read_ptr dereference.
Impact vs. prior commit (isolated light build):
ESP8266 .irom0.text: 267912 -> 267784 (-128 B)
ESP8266 .bss guard vars on light symbols: 16 -> 0 (-16 B RAM)
ESP32-IDF .flash.text: 136988 -> 136996 (+8 B, marginal)
