[verified] Remove tourism-only sections (01 surprise pulse, 02 provenance, 03 signal table, 04 research run); thesis across 3 themes; sources show fetch date

- Removed 'เชื่อถือข้อมูลได้ไหม' (02), 'ตารางสัญญาณ' dup (03), 'หลักฐานพอจะรองรับ study' (04), tourism surprise pulse — superseded by 3-theme panel + sources table
- 05 บันทึกการวิเคราะห์ now lists thesis per theme (tourism/auto/energy) with surprise
- Sources table shows fetched-at date (ข้อ 2)
- All dashboard analysis is real (no mock); automation note: no cron yet (data fetched on-demand + daily cache)
- Verified: build + browser 8 checks pass
