2026-08-07 — UI: 3-tab layout per spec (admin overview w/ date filter, personal dashboard, training, settings)

Spec (from user)

Settings page: user/profile settings + change password.
3-tab UI:
- 2.1 Dashboard ภาพรวม (admin only): overall user stats + DATE FILTER.
- 2.2 Personal dashboard: per-user results (admin also has it — admins train too).
- 2.3 Training: product list -> persona list w/ difficulty; admin sees full persona data + edit + "add product" button (generate new personas).

Tab 1 Admin overview (/) = Analytics.vue: headline stats (sessions/wins/losses/close rate/avg score/trainees) + date filter (?from=YYYY-MM-DD&to=YYYY-MM-DD on session created_at) + hardest personas + admin quick actions (Users / + Add product).
Tab 2 My dashboard (/my/board) = MyBoard.vue: win/lose/not-tried summary + recent sessions. Backend /api/me/board + /api/chat/sessions now allow ANY authenticated user (so admins can view their personal dashboard too), not just role=user.
Tab 3 Training (/training) = Training.vue: product list w/ status badge + persona count; admins see ALL groups (draft -> analyze/edit, ready -> manage), trainees see ready only; on product click -> personas list showing difficulty (1-5 stars); admins get the Manage-personas route (/admin/groups/:gid/edit).
Settings (/settings) = Settings.vue: profile (name/email) + change password + language. Added self-service PATCH /api/auth/profile (updates name/email for any authed user) + UserStore.set_name.

analytics_routes: date-range filter (from/to) on session created_at.
auth_routes: PATCH /api/auth/profile.
users.py: set_name.
me_routes / chat_routes: removed strict require_roles("user") on /api/me/board and /api/chat/sessions (still auth-gated + self-scoped).

Frontend npm run build ok (fixed a duplicate style attr in Analytics.vue that broke parse).
Backend tests m0 / setup / e2e all pass.
Live server: /api/analytics?from&to returns filtered results; PATCH /api/auth/profile updates name (200); served SPA references the fresh chunk.
Pushed to git.moreminimore.com/kunthawat/sales-trainer (b05907a).
