Fix/1448 cqc banner for subs

[duncanc19]

Issue

The CQC banner (to warn users that there is a mismatch between their data on our service and their CQC data) was not displaying when viewing subs from a parent account. This was due to it not having been implemented for subs. This PR changes the implementation of using a service to store whether to display the banner which was getting cleared when viewing a sub, to use a resolver which is used on both the parent/stand alone and sub dashboards.

Work done

• Created resolver which gets data for whether to show the CQC banner, and updated all home/workplace tab pages to use it
• Removed CQC banner code from establishment service
• Corrected localhost file path in gitignore so we can use it to store variables we don't want to push to Github
