* Simplify dispatch map
Since none of dispatches are doing any custom transformation, just use a direct map. The number of arguments for the comment function are getting crazy.
* Block: pass comment ID for deletion when being blocked.
## Issue
7003 Can't unblock if delegator deleted their channel
## Changes
- Changed the function parameter from 'creatorId' to 'creatorUri'
- It got short-circuited because we don't resolve deleted channels. But the client already have the full creator URI (containing the needed 'name' and 'id'), so there is no need to actually look at the resolved list -- just pass the uri like all the other functions.
## Issue
6712 Comment Moderation - time based bans
## Approach
- Consolidated the 3 types of blocking buttons in the comment content menu (i.e. Block, Moderator Block, Admin Block) into 1 regular Block button.
- Show a modal when Block is clicked.
- Let user choose the blocklist.
- Let user choose the timeout duration (this PR's impetus).
