fix(tk_construction_management): chatter migration + chart NaN guard + remove debug logs

- 12 oe_chatter <div> blocks migrated to <chatter/> (Odoo 18 modern pattern)
  Removes Missing widget: mail_followers/mail_activity/mail_thread warnings.
- renderGraph guards against empty/all-zero series. ApexCharts was producing
  M NaN NaN SVG paths when total=0 in donut/pie charts. Now shows No data.
- Removed two leftover console.log(..., dasdsa) debug calls in
  static/src/js/construction_dashboard.js.

User-visible: chatter renders cleanly, no SVG NaN console errors, no
debug noise.
