FlowFuse 2.31 blog: featureCatalog + changelog interlinking (stacked on #5114)

[dimitrieh]

Summary

Stacked follow-up to #5114 (the FlowFuse 2.31 release blog post). It holds the featureCatalog + changelog interlinking, which can only be correct once the 2.31 changelog entries exist (they land with the release). Keep as draft; merge after #5114 and the changelog entries are in.

This PR wires the blog's features: block to featureCatalog ids:

• ff-expert-application-building → "Agentic Development Now in Open Beta"
• certified-nodes → "Certified nodes for industrial connectivity and AI"
• "What else is new?" tiers row

The features: block alone does NOT link up

Verified against the releaseFeatures transform in .eleventy.js: badges come from each feature's cloud/selfHosted tiers in featureCatalog.yaml; changelog links come from that feature's changelog entries filtered to release: "2.31". So this PR must also edit featureCatalog.yaml, otherwise the blog shows no changelog links and stale/wrong badges.

ff-expert-application-building

• Add a release: "2.31" changelog entry (URL must match the authored agentic open-beta changelog page). Without it, no changelog link renders (the existing 2.30 entry is filtered out for 2.31).
• Set selfHosted.enterprise.value: true so the Self-Hosted Enterprise badge shows (currently all null → no SH badge). Cloud already resolves to "All tiers".

certified-nodes

• Add a release: "2.31" changelog entry (URL must match the authored certified-nodes changelog page; currently changelog: null).
• Badge decision: the catalog has selfHosted.enterprise: true, so the blog would render a Self-Hosted Enterprise badge, but certified nodes is Cloud-only for 2.31 (SH deferred). Pick one: (a) accept it, (b) set SH null until SH support lands, or (c) use an inline cloud-only tiers: entry in the blog instead of the id (loses the changelog link).

Changelog entries + docs that must exist for the links to resolve

• Agentic application building, open beta (2.31)
• Certified nodes (2.31)
• AI opt-out, per-team / per-instance (Create a changelog entry for the ai opt out feature flowfuse#7333)
• LLM nodes docs (docs: add LLM nodes documentation for FlowFuse AI section #5136) — the blog links /node-red/flowfuse/ai/llm-nodes/
• Custom CA certs docs; AI opt-out / feature-flag docs

@sumitshinde-84 does this cover everything on the changelog and docs side for 2.31, and any preference on the certified-nodes Self-Hosted badge question above?

does this cover everything on the changelog and docs side for 2.31, or is anything missing?
I think yes !
