fix: use of fatal, double error output and vague errors

[gotbadger]

Description

When bearer.ignore is invalid you would receive an error like.

Error: unexpected end of JSON input
unexpected end of JSON input
exit status 1

This PR:

• Improves error handling for invalid bearer.ignore files to give more context
• Fixes issue where the error was printed twice
• Fixes some cases where errors resulted in a immediate call to fatal that did not flow though the normal framework error handling

New output

Error: ignore file '/My/Path/bearer.ignore' is invalid - unexpected end of JSON input
exit status 1
