fix(i18n): clear the accumulated drift in the generated translation bundles

The committed bundles had fallen behind the spec on three independent axes. os i18n extract (merge mode — every existing translation is preserved) reconciles all of them:

Keys the spec no longer has, still carrying translations in *.metadata-forms.generated.ts. All three were removed deliberately and are now rejected by the schema, so their entries were dead weight:

• capabilities.trash / capabilities.mru — enable.trash/enable.mru retired in the 16.x line (#2377), with tombstone guidance in UNKNOWN_KEY_GUIDANCE.
• agent visibility — removed 2026-07 (#1901).

Keys the spec gained but the bundles never learned: the summaryOperations.* sub-fields (object / function / field / relationshipField / filter), and sys_invitation.business_unit_id / positions from the ADR-0105 D8 placement work.

Objects stuck on empty strings. sys_migration's labels and help text were committed as "" in the ja-JP and es-ES bundles, which renders as blank in those locales rather than falling back to anything readable. They now carry the schema text like every other untranslated key.

No API or schema change — this only affects what the UI displays.
