Dark theme follow up issues

Awesome! Small stuff, but:

• E2E icons should use primary/notice colours (fixed in matrix-org/matrix-react-sdk@feb9295)
• Vertical bar splitting top right icons isn't skinned (should we take the primary icon colour and apply 50% opacity?) (fixed in matrix-org/matrix-react-sdk@4409636)
• (+) icons in room list not skinned
• @mention backgrounds not skinned (for now using the room highlight bg would be ok) (fixed in matrix-org/matrix-react-sdk@4227500)
• Adjust gradient to use rgba for Safari (fixed in matrix-org/matrix-react-sdk@5f6907c)
• Change box shadow on top left menu to use bg value (fixed in matrix-org/matrix-react-sdk@f64f39f)
• LLP should be #15171B not #1C1F24 (subtle, but important to establish the same depth hierarchy as the light theme)
• E2E composer decoration, and message hover decoration should use new palette (we're missing a yellow, maybe use the orange if we don't have a yellow when you tackle this)

• Tweak color values to v2 from Nad (fixed in matrix-org/matrix-react-sdk@e09963c)

• Markdown button status appears reversed
  
• Should there be a more visible vertical line here?
  
  
• It would be nice to use a white [m] logo in the room directory
  
• "INVITED" in user list is hard to see (Set h3-color in dark theme matrix-org/matrix-react-sdk#2656)
  
• Room settings that you can't update are hard to read
  
• Safari scrollbars are dark but (one of the) Firefox scrollbars is light. Which is intended? Is Gemini getting killed before 1.0?

Can I chuck in:

• <pre> blocks have black text on a black background

• Widgets blend in with the timeline

@jryans re widgets blending; they should be using the header/panel background colour

(could people put names next to their issues if possible so I don't have to mouse over all of them?)
