fix: 完善转发引用解析与图片回退并支持配置化控制 (#5054)

* feat: support fallback image parsing for quoted messages

* fix: fallback parse quoted images when reply chain has placeholders

* style: format network utils with ruff

* test: expand quoted parser coverage and improve fallback diagnostics

* fix: fallback to text-only retry when image requests fail

* fix: tighten image fallback and resolve nested quoted forwards

* refactor: simplify quoted message extraction and dedupe images

* fix: harden quoted parsing and openai error candidates

* fix: harden quoted image ref normalization

* refactor: organize quoted parser settings and logging

* fix: cap quoted fallback images and avoid retry loops

* refactor: split quoted message parser into focused modules

* refactor: share onebot segment parsing logic

* refactor: unify quoted message parsing flow

* feat: move quoted parser tuning to provider settings

* fix: add missing i18n metadata for quoted parser settings

* chore: refine forwarded message setting labels
