Replaces flat warning strings with machine-readable FieldIssue objects
(code, field_name, message, severity) emitted during compose and surfaced
in all migration result paths via a new field_issues[] key.
Codes: CROSS_RECIPIENT_CONDITIONAL, UNSUPPORTED_OPERATOR, HIDE_ACTION,
MULTI_PREDICATE, INVALID_PARENT_TAB, FIELD_TYPE_SKIPPED, PARTIAL_FIELD_TYPE
Cross-recipient conditional detection: compose now builds a field→assignee
map and flags conditions where the trigger field belongs to a different
recipient — the main cause of the CONDITIONALTAB_HAS_INVALID_PARENT 400.
UI changes:
- Success rows with field_issues show ⚠️ icon + amber "partial" badge
- Results, History & Audit, and Template Detail history tab all show
field issues grouped by code in collapsible sections within expanded rows
