Fix error pages overlapping with nav drawer (#887)

## Description
As of #842, if an error occurred on some pages that display a generic
error message, it would be shown under the nav drawer making it
difficult to read.

This PR fixes that by passing the `modifier` into the `ErrorMessage`
composables ensuring it has proper offset & padding. Also, for
consistency, passes it the `LoadingPage`s.

### Related issues
Caused by #842

### Testing
Threw an exception during home page loading to observe the issue and fix
on the emulator

## Screenshots
N/A

## AI or LLM usage
None
