[management] State the sqlite precision caveat without the review history

A comment explaining why the truncation guard sits on the type recorded how
the gap came to be noticed rather than the constraint itself, which AGENTS.md
rules out. The technical point is the one worth keeping: sqlite preserves
nanoseconds, so a sqlite-only suite cannot observe the truncation.

The neighbouring back-compatibility comment gets the same treatment — "clients
written before this existed" leans on the reader knowing what "this" was, and
naming conditional requests outright says it plainly.

 Note: The anonymized IP addresses in the status file do not match those in the log and routes files. However, the anonymized IP addresses are consistent within the status file and across the routes and log files.
 
+MAC Addresses
+MAC addresses are replaced at every anonymization level with consistent placeholders counting up from 02:00:00:00:00:01. Broadcast, multicast, and all-zero addresses are kept. At the default level a preserved IPv6 link-local address may still embed a MAC address (EUI-64); the strict level anonymizes those addresses.
+
 Domains
 All domain names (except for the netbird domains) are replaced with randomly generated strings ending in ".domain". Anonymized domains are consistent across all files in the bundle.
 Reoccuring domain names are replaced with the same anonymized domain.
+At the strict level, the peer name labels in front of netbird domains are anonymized as well.
