config/distributions: plucky -> eos, resolute -> supported

[igorpecovnik]

Summary

Routine maintenance of config/distributions/*/support flags:

• plucky → eos — Ubuntu 25.04 is a 9-month interim release that Canonical EOL'd on 2026-01-25 (three months ago). Keeping csc status produces images against an archive that no longer receives security updates.
• resolute → supported — Ubuntu 26.04 LTS just released and has been running as csc for at least one cycle. Promote alongside noble and trixie so the desktop matrix audit and other consumers treat it as a first-class supported release.

Current state before this PR:

release	support
noble	supported
trixie	supported
resolute	csc → supported
plucky	csc → eos

Test plan

• grep -l supported config/distributions/*/support lists noble, trixie, resolute
• grep -l eos config/distributions/*/support lists bullseye, buster, focal, oracular, plucky
• configng's desktop matrix audit picks up resolute as a supported release on its next run
