Improve the user experience around displaying the pins table in the account section

[joshJarr]

Acceptance criteria:

• I want to be able to see all my pins and their state
• If I have pinning enabled, I want to see the pins table (whether I already created pins or not)
• The behavior is consistent with REST APIs, if I don't have access to PSA I won't see the table in the UI.

Notes

Upon logging in with a user without PSA enabled, a redundant call is made to the /pins endpoint to fetch user pins.
We should be able to avoid this by checking the user HAS_PSA_ENABLED flag.

Note: we need to double check these criteria before starting work on them
