Include configured channel models without creating metadata, derive square
visibility from live routes and metadata policy, and filter before pagination.

Share pricing display with the model square, show expression tiers and task
unit prices, preserve zero rates, and expose full pricing and visibility
reasons from compact responsive rows. Complete all seven locale translations.

Validated frontend tests, typecheck, lint and production build, plus the
model database matrix on SQLite 3.50.4, MySQL 5.7.44 and PostgreSQL 9.6.24.
