feat: add patchNodeField operation for surgical string edits (v2.46.0) (#698)

Add dedicated `patchNodeField` operation to `n8n_update_partial_workflow`
for surgical find/replace edits in node string fields. Strict alternative
to the existing `__patch_find_replace` in updateNode — errors on not-found,
detects ambiguous matches, supports replaceAll and regex flags.

Security hardening:
- Prototype pollution protection in setNestedProperty/getNestedProperty
- ReDoS protection rejecting unsafe regex patterns (nested quantifiers)
- Resource limits: max 50 patches, 500-char regex, 512KB field size

Fixes #696
