policy(2026-11-01): publish the three new commercial promises

- terms.html: cancel any time + refund unused time (pro rata); delete the
  no-refund sentence and the 'no refund promise beyond' clause
- terms.html: prices are tax included (was 'plus tax where it applies')
- index.html: order widget #orderPlanTax text '+ tax' -> 'tax included'
  (id/class kept; static text, no JS reads or writes it)
- support.html: add the AI-agent-urgent + 24h email support promise,
  bot still scoped to quick fixes
- odoo-erp-automation-bootcamp/index.html: seat transferable any time,
  cancellable up to two weeks before the 21 Jan 2027 start
