feat(api): PATCH /dictionaries/{name}/schema — inline non-breaking field edit (backend #4)
Backend #4 из pending-endpoints brief. Frontend Fields tab inline edit:
кликаешь field row → form показывает только allowed (non-breaking) changes
→ submit → patch component bumps (1.4.0 → 1.4.1) без full DictionaryEditorDialog.
Body:
```json
{
"expectedHeadVersion": "1.4.0",
"field": "altitude",
"changes": { "description": {"ru":"Высота орбиты"}, "minimum": 0 }
}
```
Allowed change keys: description / title / minimum / maximum / enum.
Breaking keys (type/format/x-references/etc) → 422 breaking_change_requires_draft.
Validation:
- minimum tighter than current → 422 validation_failed (могло бы invalidate existing)
- maximum tighter than current → 422 validation_failed
- enum removing existing values → 422 (only additions allowed inline)
- expectedHeadVersion != actual → 409 version_mismatch (optimistic lock)
Implementation:
- PatchSchemaRequest DTO (record).
- SchemaPatchService: gates dict/scope/version, applies whitelisted changes
on deep-copied JsonNode, bumps patch component via bumpPatchVersion helper
(semver-safe + fallback для non-semver).
- DictionaryDefinitionController новый @PatchMapping.
- OrdinisException.unprocessableEntity helper (422).
Audit: hooks через existing AuditLogger.definitionUpdated после save.
Tests +10: 4xx scenarios, description update bumps version, enum add ok,
enum remove blocked, minimum expand ok / tighten blocked, version bump
helpers (semver + non-semver fallback).
