Setup Sessionize event for CFP

[matrixise]

Context

The CFP page is live but submissions are not yet open. We need a Sessionize event configured before the CFP can open.

Task

• Create the PyCon Ireland 2026 event on Sessionize
• Configure talk formats (30-min talk, 5-min lightning talk)
• Set CFP open and close dates
• Set speaker notification date
• Add the Sessionize submission link to the /cfp/ page
• Update cfpStatus in hugo.toml from "soon" to "open" once live

Priority

ASAP — required before CFP can open.
