Metadata uploader restrictions

[ksierks]

Description of changes

Changes made to the "Map Headers" Step:

• displayed sample name list in a drop-down
• displayed headers table on header selection
• made headers table scrollable
• changed restrictions to a radio button group
• pre-populated restrictions if field already exists

Other changes:

• removed trailing & leading whitespace from data files
• stored state in seperate sessions for each project (expiry is 6 hours)
• cleared state on import initialization
• removed auto redirect at completion
• changed button on completion to navigate to projects page
• ensured metadata fields, restrictions, & entries are updated if they already exist
• created new api endpoint to create metadata fields & restrictions before entries are created to solve race condition
• prevented import from happening to locked samples

Note: I will create a separate PR for tests

This is a really great start, I am liking how it is going. I made a couple UI suggestions that might get the page to work a little bit better.

I tested this out and it works as expected. I have a few comments on code naming and code structure.
