Previously load() returned true unconditionally on file-open success, masking truncated or corrupt /regions2 files. Additionally, the first field of each entry record (r->id) used the same success-chaining pattern as subsequent fields, so a clean EOF at a record boundary set success=false and would have been indistinguishable from real corruption once the return value was fixed. The r->id read is now split out: n==0 is a clean EOF (break, success retains its prior value from the header read), n!=sizeof(r->id) is a partial read or corruption (break, success=false). load() now returns success instead of an unconditional true, so its return value reflects the actual parse outcome. Companion fix to meshcore-dev#2372, which fixed the same return-true hardcoding in save(). (meshcore-dev#1891 originally reported this on load() but was closed when meshcore-dev#2372 landed — that PR only touched save(); this addresses the load() side.)

Companion fix to #2372, which fixed the same `return true` hardcoding
in save(). load() has the same issue — it ignores read failures and
always returns true regardless of what happened during the read loop.
(Note: #1891 originally reported this on load(), but was closed when
#2372 landed — that PR only touched save(). This PR addresses the
load() side.)
Fix distinguishes:
a variable-length region list, success unaffected
real failure, success=false
Verified on Wio Tracker L1 Pro (companion firmware): wrote 3 regions
via `region put`, rebooted, confirmed all 3 persisted correctly after
reboot — the clean-EOF path in load() does not regress normal loads.
