Yuan Li 3c21fed099 fix(bluebubbles): cap _guid_cache with LRU eviction to prevent unbounded growth
The _guid_cache dict grows without bound as new contacts/groups are
resolved.  In a long-running gateway instance with many unique targets
this becomes a slow memory leak.

Replace the plain dict with an OrderedDict capped at 500 entries.
When the cap is exceeded the oldest (least-recently-used) entries are
evicted.
