Reorganise token features into sub navigation

[pennyandrews]

The Chore

• [ ] There is a Token Home with existing landing page content
• [ ] Under VEGA token is a submenu / nav with:

• Supply and vesting
• Withdraw assets
• Redeem vested tokens (not in nav though? Or?)

• [ ] "Supply and vesting" links to the tranches page that's currently not in the nav
• [ ] "Withdraw assets" links to the withdrawal page
• [ ] "Redeem vested tokens" links to the redeem page [if it's in the nav...]
• [ ] There is a useful and functioning version that works with no wallets connected

Tasks

• [ ] What do we need to do first
• [ ] and then what?
• [ ] Etc.

Additional details / background info

A little bit of repetition with ticket 2033 :)

On XSM ↳ MD the nav collapses into a drawer. On XSM ↳ MD - if the current page is a sub-item of "Token" then expose the sub-items by default with the current page nav item set as active.

Figma link here ↳

Note: The active state underline on XSM ↳ MD is closer to the text than on <XL due to the vertical spacing between items. The hover state (on <XL) is white, with no underline. The default state is light grey.
