🐛 Wrong voting power numbers for retired dReps

### Area

### Domain

### Which wallet were you using?

_No response_

### Context

I was just scrolling through the dRep directory and was kinda mind blown by the amount of retired dReps with active delegation. Turns out: the displayed data is dead wrong though, there are only 3 retired dReps with active delegation.

Probably a missing cronjob that updates delegation even for retired dReps?

(I'd suggest a little UI tweak anyways: show retired dReps only if actively selected, they are of no interest if you browse the dRep Directory to find a dRep to delegate to...)

### Steps to reproduce

1. Go to https://gov.tools/drep_directory
2. Look for retired dReps
3. Check their delegation
4. Find the displayed amounts are wrong

### Actual behavior

Wrong / outdated (?) delegation amounts / voting power is shown.

### Expected behavior

Display correct voting power, even for retired dReps.
