fix(autofix): Show Add Integration CTA when no coding agents installed (#112625)

The coding agent dropdown in the autofix next-step UI was gated on
`codingAgentOptions.length > 0`, which meant the "Add Integration" CTA
link inside the dropdown footer was only visible to orgs that already
had
at least one coding agent integration installed. Orgs with zero
integrations had no way to discover or install one from the autofix
flow.

Changed the guard to render the dropdown whenever
`codingAgentIntegrations`
is defined (i.e. the current step supports coding agents), regardless of
whether any are installed. The dropdown now shows the "Add Integration"
footer link even when empty, directing users to the integrations
settings
page.
