Node page cosmetic updates + widgets

Figma

Some minor changes to the Node page:

• changes in button icons and states
• updated dropdowns style
• default table styling (eg. labels from muted -> foreground)
• on-chain fees widget moved from Home
• routing widget moved from Home
• blockheight widget moved from Home

Completely new:

• Events table Alby Hub Events table #848

Optionally:

• show routing fees only If user already has public channels. If not, then Blockheight can be next to On-chain fees
• If events table can be paginated, then widgets can be below it

Events table is not possible right now, so it's good to keep this as a separate issue.
