Add a command to query all open positions in a PCLI wallet

[cronokirby]

Closes #4825.

Describe your changes

This adds a command: pcli v lps which displays all open liquidity positions owned by the wallet.

To test, try, e.g:

pcli tx position replicate linear --lower
-price 0.4 --upper-price 0.8 penumbra:gm 100gm --current-price 0.5

pcli v lps

Works great!

I tacked on one small change, renaming the option to be pcli view liquidity-positions, but preserved the shorthand version as an alias, so pcli view lps still works:
