Redesigned Plans page with annual/monthly toggle and add-ons

We have created a redesigned Plans page so picking the right combination of products is easier.

• The free plan card shows the included streaming minutes, encoding minutes, and views; paid plans are usage-based and billed by what you actually consume.
• The “billed annually” wording was reworked to be unambiguous about the savings vs. monthly pricing.
• A trial expiration date displays prominently for Cloud Playout users on a trial so it is clear when the trial ends.
• AI Agents (Notes, Search) plan rows show a Beta tag so users know the pricing may change.
• You can switch between plans directly from the page.

Plan changes use the standardized confirmation modal and surface prorated cost before committing.
