ci: make lockfile and render checks blocking

[dmcilvaney]

alzdev comp render should also be deterministic so drop regex filtering for dates as well.

Pull request overview

This PR tightens CI enforcement around generated artifacts by making rendered-spec drift and lockfile drift checks blocking, and by removing the previous “timestamp-only noise” exception so azldev component render output must be deterministic.

Changes:

• Remove continue-on-error from the render + locks update steps and add an explicit “Fail on lock drift” gate.
• Remove the “disregard this comment” warning banners from both drift PR comment formatters.
• Remove changelog date regex normalization from the rendered-spec drift checker (treat all diffs as real).

Generally LGTM. Provided some non-blocking feedback offline to evaluate whether we want to pursue.
