Feature: Admin v2 flag details page

[KevinMulhern]

Because:

• We are building a new Admin system and need a flag details page where we can handle individual flags
• related to https://github.com/TheOdinProject/top-meta/issues/291

• This commit:

• Adds a flag details view
• Flag actions will be chosen from a select instead of displayed as separate buttons

New UI for selecting choosing what action to take:

Overall Page:

Acceptance criteria for QA

Review app link - https://odin-review-app-pr-4470.herokuapp.com/admin_v2/flags

Create a flag:

1. Log in as a normal user - kevin@odin.com, password
2. Go to the recipes project solutions and flag one of the solutions.

View flag in admin v2:

1. Visit /admin_v2 and sign in with admin@odin.com and password123
2. Visit flags from the side nav
3. There should be 1 active flags in the table
4. View that flag by clicking on the view link

Note: Choosing an option to resolve a flag will show an alert for now. Getting those options working will be the next PR.
