feat: Switch to outline icons

[artonge]

Fix #3126

Two questionable icons:

• No outline for Albums icon in material design icon. Will ask if we have a solution to use the material symbols already

• Should the star icon when favoriting be filled, and outlined when unfavoriting? @kra-mo any opinion?

How about https://pictogrammers.com/library/mdi/icon/image-multiple-outline/ for the album?

Should the star icon when favoriting be filled, and outlined when unfavoriting? @kra-mo any opinion?

For Talk @jancborchardt and I decided it would reflect the state, so filled when favorited (-> "to unfav" action)

Nice! Agree with @AndyScherzinger 's review. :)
