Make it easy for user to know on the proposals listings page if they have a proposal ready for processing

[jdville03]

For some adapter types (e.g., Onboarding, Tribute, TributeNFT) only the original proposer can process the proposal if it has passed. It should be easier for a user to know if one of their proposals is ready for processing when viewing a proposals listings page. Some ideas short of a more robust app-wide notification UX:

• "ready for processing" category on listing page
• make the connected user's ready-to-be-processed proposal on the listing page more prominent (e.g., thicker border, different background, animation, place it at top of category)
• if the connected user has a proposal that is ready to be processed then there is some sort of alert/notification flashed or made prominent at the top of the proposals listing page on load
