fix(env_state): changelog triggers skip a service's internal tables

[earakely-scale]

Summary

_install_changelog_triggers put a row trigger on every table in a service's schema except _changelog itself. A service's internal tables carry the same leading underscore and hold no domain rows. The first such table is the file-bytes table a server now keeps next to its rows, and a row trigger there would copy whole blobs into changed_fields on every upload. Skip every underscore-prefixed table, the way _changelog already was.

Testing

Unit test on the rendered SQL. The companion synthetic-servers change was exercised end to end in dev with this installer in place: writes to the servers' _files tables left the changelog empty.

Closing: the file store in synthetic-pipelines #1440 ships without a framework-side trigger exclusion; the changelog trigger on the servers' internal file table is accepted as is.
