Summary: Fixes T6692. Addresses two main issues: - The write guard would sometimes not get disposed of on exception pathways, generating an unnecessary secondary error which was just a symptom of the original root error. - This was generally confusing and reduced the quality of reports we received because users would report the symptomatic error sometimes instead of the real error. - Instead, reflow the handling so that we always dispose of the write guard if we create one. - If we missed the Controller-level error page generation (normally, a nice page with full CSS, etc), we'd jump straight to Startup-level error page generation (very basic plain text). - A large class of errors occur too early or too late to be handled by Controller-level pages, but many of these errors are not fundamental, and the plain text page is excessively severe. - Provide a mid-level simple HTML error page for errors which can't get full CSS, but also aren't so fundamental that we have no recourse but plain text. Test Plan: Mid-level errors now produce an intentional-looking error page: {F259885} Verified that setup errors still render properly. @chad, feel free to tweak the exception page -- I just did a rough pass on it. Like the setup error stuff, it doesn't have Celerity, so we can't use `{$colors}` and no other CSS will be loaded.
