Improve Sorting of Bonds by Epoch in Chronological Order

[amadison79]

When running the command namadac bonds --validator $alias, the list of bonds appears to be displayed in an arbitrary order. It would be more intuitive and user-friendly if the entries were sorted in chronological order, starting from the earliest epoch (epoch 0) to the most recent.

Justification:

• This improves data readability, especially when there are many bonds.
• Users can more easily track the evolution of bonds over time.
• It aligns the presentation with other similar commands that follow a natural order.

For example, instead of:
Remaining active bond from epoch 15: Δ 135.000000
Remaining active bond from epoch 0: Δ 135.000000
Remaining active bond from epoch 17: Δ 100.000000
Remaining active bond from epoch 4: Δ 135.000000

The bonds should be displayed like this:
Remaining active bond from epoch 0: Δ 135.000000
Remaining active bond from epoch 4: Δ 135.000000
Remaining active bond from epoch 15: Δ 135.000000
Remaining active bond from epoch 17: Δ 100.000000

This adjustment would significantly improve readability and usability for users.

Thank you for considering this suggestion!
