fix(replication): preserve normalized replica metadata

Browse Source 
Restore only the six replication-specific metadata fields after trust
validation, so streaming uploads retain their actual content encoding and
Snowball entries do not inherit ordinary metadata from the outer archive.

Include helper, authenticated PUT/COPY/multipart and Snowball regressions,
plus the R7 investigation, actual Opus 5 consensus and local verification.
The production change is based on PR #187 by Mikhail Khadarenka.
