fix: cannot automatically get embedding dim when create embedding provider (#5442)

* fix(dashboard): 强化 API Key 复制临时节点清理逻辑

* fix(embedding): 自动检测改为探测 OpenAI embedding 最大可用维度

* fix: normalize openai embedding base url and add hint key

* i18n: add embedding_api_base hint translations

* i18n: localize provider embedding/proxy metadata hints

* fix: show provider-specific embedding API Base URL hint as field subtitle

* fix(embedding): cap OpenAI detect_dim probes with early short-circuit

* fix(dashboard): return generic error on provider adapter import failure

* 回退检测逻辑
