feat: consistent runepool read-only behaviour

[gomesalexandre]

Description

RUNEPool is no different than other savers, it's going away in prop6 with funds going into DLP.
Yes, the only diffence with savers is you can still deposit, but we don't want our users to be rugged by depositing and then being stuck.
As such, make its flow consistent with savers.
