feat(config): add UI metadata to remaining ChatConfig fields (Wave 2)

- plan_reply_log_max_per_chat: input widget + file-text icon
- llm_quote: switch widget + quote icon
- enable_talk_value_rules: switch widget + settings icon
- talk_value_rules: custom widget + list icon

All ChatConfig fields now have json_schema_extra metadata for complete UI visualization support.
