Fix various bugs in dashboard metrics

[JamesNK]

Description

I started fixing a reported bug in the metrics area and found a bunch more while testing. They're all minor fixes and this PR rolls them up together.

Changes:

• Meter list of instrument links now includes the selected duration and view in the link
• Fix disabled headers on metrics and exemplars grids. Aspire headers should only be used when a header is resized/sorted.
• Fix select duration not being correctly saved and restored from session state.
• Fix JS error when navigating away from metrics graph. No impact on the app, but it's messy to have unnecessary JavaScript errors.

Fixes #5466
