Unify frontend config, fix marketing tracking field mismatch, expose customer notes in API

Centralizes all hardcoded page paths, storage keys, external URLs, and branding into a single uni-app/src/config.js. Fixes trackMarketingEffect sending wrong field names (action/content_preview -> event_type/content) that silently dropped tracking data. Adds notes, estimated_value, next_followup_at to Customer response. Removes '翻译' from bottom tab nav (5 tabs now), adds quick translate card on home page. Makes profile page header color consistent with app theme (#1890ff).
