[codex] Hide CFP speaker callout on home page

[NoamEfergan]

What changed

Removed the home-page fallback that rendered the CFP speaker callout when no speakers were announced.

Why

The site should no longer show the "We are looking for speakers" call for papers section on the home page.

Impact

When speakers exist, the speaker section still renders as before. When no speakers exist, the home page now skips the CFP callout instead of linking visitors to /cfp from that section.

Validation

• Confirmed the working tree only includes Resources/Views/Home/home.leaf.
• Attempted swift build, but stopped it after several minutes while SwiftPM was still fetching the large aws-sdk-swift dependency and had not reached compilation.

This is somewhat intentional, it's all synced to Sessionize and as soon as we populate speakers it'll switch modes

[adamrushy]

I wonder if it's better to just change this title:

So it better reflects the state of Sessionize, but keep the "Learn more" button because this takes people to a full page on CFP that explains how the process works, WDYT?

[Sherlouk]

We'd need to start caching that state somewhere, wouldn't want to put the main homepage behind Sessionise API as that'll just lead to rate limits and more error cases

Yeah, easy enough to do right - could even stick it in the DB that's cache for X days or even weeks to be honest as it doesn't change that often

Get codex on it Nowham

Maybe save it on the event obj

[NoamEfergan]

Implemented the event-level CFP flag on this branch.

Changes:

• Added Event.cfpClosed backed by a new cfp_closed column with default true.
• Added and registered EventMigrationV7.
• Exposed cfpClosed to Leaf via EventContext.
• Updated the home page to show Home/_cfp only when there are no speakers and cfpClosed is false.
• Added a CFP closed? switch to the admin event form and persisted it through the event controller.

Validation:

• git diff --check passes.
• Attempted swift build in sandbox and with elevated permissions, but both runs stayed in the aws-sdk-swift dependency fetch phase and were stopped before compilation. swift test was not run because build never reached compile.

looks good, let's push to staging and test

[NoamEfergan]

@Sherlouk i've had to add a rule there because deploy can't happen on forked PRs. if it's wrong let me know, i think you need to approve the deply

Merging into an org-owned branch for testing
