ui: get rid of bootstrap

Tests (pass 1)

[x] REP/21.11: Tabs (patron profile, doc detailed view, document search, etc) -> inactive tabs could be grey like in native prime-ng

[x] REP/21.11: Autocomplete: the order of the suggestions is not the same as ILS-TEST, why?
[x] REP/21.11: It is great that we can scroll inside the autocomplete suggestions but the panel could be a little bit taller still so that more suggestions are visible?
[x] REP/21.11: Facets regression - I need to click on the "plus" to expand a facet. It would be better if the whole facet was clickable to expand like before.

[x] REP/21.11: The order of the tabs is inverted
[x] REP/21.11: Editor - The space between rows is a little bit too large
[x] REP/21.11: Editor - There is a double border on dropdown fields (e.g. Country, gender)
[x] REP/21.11: Loans tab : badges (e.g. 1 renewal, due date soon) should be another color (too much blue), grey like before ?
[x] REP/21.11: Patron profile, some tabs content seems to not load correctly when changing tabs. When switching to "interlibrary loans", it stays stuck on "loading in progress" for minutes
[x] REP/21.11: When switching organisations, the badge with number of interlibrary loans is not updated.

[x] REP/22.11: Documents brief view
- [x] Button "Export as" does nothing unless clicking the arrow, make the entire button functionnal?
- [x] Button "Export as" is in a different design than the one in the detailed view
- [x] MD: wrong display of the contributions when more than one (the ';' is missing). Ex: https://ilsdev.test.rero.ch/aoste/search/documents?q=contribution.entity.authorized_access_point_fr:%22Boehlen,%20Franz%22&page=1&size=10&sort=bestmatch&simple=0
[x] REP/22.11: Document detailed view:
- [x] "interlibrary loan" button is missing
- [x] button "request another issue" (holdings request) is missing from the holdings component
- [x] Request item component -> double border on dropdown
- [x] Button to expand a holdings should be on the left and be standardized with other expand buttons (e.g. in patron profile)
- [x] [nice-to-have] Click anywhere on a holding to expand?
- [x] [nice-to-have] holdings component header could be light gray

[ ] REP: The color of the header for an organisation view is not taken into account : https://ilsdev.test.rero.ch/aoste/
[ ] REP: Patron profile editor -> "Save" button does not work. It doesn't save my modifs and doesn't redirect.
[ ] REP: Search view "No option available" is displayed for a microsecond during loading (e.g. when changing the sort order). Either display a spinner or nothing at all.
[ ] REP: Patron profile: text for buttons in the "Personal data" becomes unreadable when hovering
[ ] REP: Merge "edit profile" and "change password" apps
[ ] REP: Document detailed view tabs in ANgular
[ ] REP: facets: reduce font size (and spacing?)
[ ] REP: TODO decide what to do about export formats functions
[ ] REP: When requesting a holdings, the error should be a warning
