Custom per-record action buttons stay English on a localized app (transitions, generates, Duplicate & co.)

[delchev]

Observed live on a Bulgarian-localized generated app: the per-record action buttons stay English while everything around them is translated - the transition buttons (Void), the create-from buttons (Save as Template, Record Reminder), and the built-in Duplicate (plus a set of chat/upload strings).

Two independent gaps:

• The generated catalog template misses nine defaults.* keys the views reference (duplicate, send, status, system, internal, internalNote, writeMessage, upload, uploading) - T() silently falls back to the English default and downstream language catalogs never see the keys.
• The transition/generates action descriptors carry no translation key: the renderer already supports T(action.translation.key, action.label), but the generated descriptors emit only the raw label, so it renders verbatim.

Fix.

• The nine keys land in the catalog template.
• The descriptors carry translation: { key: "<project>:<model>-model.actions.<name>" }; EdmIntentGenerator puts a customActionLabels map on the .model root (one label derivation shared with the descriptors - authored label: else humanized name), and the template engine's translate action folds it into the generated en catalog's actions section - so downstream language catalogs cover the buttons like any other label.

The BPM task form's own labels (Approve) are a separate untranslated surface - #6522.
