Subject: [PATCH] [time] Fix timezone_offset() and recalc_timestamp_local()
 always using UTC fallback

time.h was missing #include "esphome/core/defines.h", so USE_TIME_TIMEZONE
was never defined when compiling time.cpp. Both functions always took the
#else path, returning 0 offset and treating local time as UTC.
