fix(site): correct prices, drop every discount claim and repair trial copy

Applies the 16 findings the user answered in projects/active/odoo-hosting-2027-landing/
decisions-2026-10-21-user.md, using the wording from
copywriter/out/site-fix-wording-2026-10-21.md.

index.html: Powerhouse 535 -> 595 in the card and in the JSON-LD Offer; delete the
three Save 8%/9%/10% badges and the empty badge div on the Empire card; replace the
'Save 15% with yearly billing' line and the coupon message text (ids kept - script.js
reads them); delete the FREE TRIAL coupon input block; qualify the checkout line as
'Card required to buy, not to start'; fix 'redundant slots' to the real rotating-slot
model; drop the 'coupon codes for startups and NGOs' promise; add Privacy and Terms to
the footer.

email/trial-confirmation.html: stop promising backups, domain mapping and SSL on the
trial (the trial has none); state what the trial is not; copyright 2024 -> 2026;
repoint Privacy/Terms from the 404 /legal/privacy and /legal/terms to the new pages.

support.html: state that custom and OCA modules install from On the Rise up and that
Side Hustle has no module installation.

odoo/upsell.html: '4 weeks free' -> '30 days free'.

blog: the backup speed-run no longer sends readers to a non-existent hosting
dashboard; my-first-post loses the 30-day refund promise and the dashboard domain
step; community-vs-enterprise-cost quotes $214/year instead of $19.40/month;
odoocommunity-agents drops 'per-seat licensing' from the body and both meta
descriptions.

sitemap.xml: add /privacy.html and /terms.html.
llms.txt: publish the Powerhouse price and list the two new pages.

Evidence: every old string verified gone and every new string present in the working
tree; 12 HTML files tag-balanced; JSON-LD and sitemap XML valid.
