Story voting

[mattddean]

• Votes table to track who voted for what and to prevent double-votes
• Authentication required to vote
• Cannot downvote own story
• Karma incremented/decremented on vote creation/deletion

Decisions:

• Story points could be inferred/generated from votes, but leaving the points column in place for now since stories begin with one point and ai-generated stories do not have a user. An alternative is to remove the points column, create a view on stories and votes to keep a votes tally, start every story at 0, and add 1 to the value in application code on retrieval to account for the implicit self-upvote on each story. But for now, this seems overly-complex compared to just maintaining the points separately. And transactions will help once supported.
• We could do something similar with user karma, but again, it's overly complex and doesn't leave much room for abuse adjustments.
• A vote is created on story creation to leave room for the above ideas in the future, and to allow a single check to prevent both upvoting your own story and upvoting a story twice.
• Balanced immediate click feedback with avoiding larger client component scope by removing the vote/downvote buttons on click, but allowing revalidatePath to update the rest of the story entry:
