Describe your changes

This is a review on consensus params template defaults which are a bit dated like @dynst noticed.

The diff of changes:

  • We align evidence retention on the staking component's unbonding_delay (about 130k blocks, 650k seconds)
  • we limit the evidence portion of a block to 30KB
  • it updates the default epoch_duration to 17280 blocks (about 1 day at 5s/block)

We implement validation in a follow-up PR (#4627)

So far so good. Thanks for taking the time to annotate the default values with descriptive comments. Standing by to provide final review, after which I'll incorporate any changed values into the migration script for #4614.

This closes #4635!

@faddat There aren't any issues with a 1MiB block size and a 30KB evidence limit, right?

I will follow up with putting the template defaults into consts that can be pulled from the app crate.
