[OGUI-1892] Disable level buttons for shifter users on page load and after

[graduta]

I have JIRA issue created

• branch and/or PR name(s) includes JIRA ID
• issue has "Fix version" assigned
• issue "Status" is set to "In review"
• PR labels are selected
• FLP integration tests were ran successful

PR which:

• if user authenticated has a role of "shifter" but not "admin":
  • the UI will disable the buttons changing the "level" of messages filtering system
  • even if the URL contains a higher level, this level will be brought back to level 1 (operations)
• adds tests to validated newly added changes
• adds const/enums for roles and infologger levels
• extracts button into a reusable component and defines objects for existing filters
