fix: limit receive addresses to 2kb

[faddat]

Description

Adds limitations to the length of ibc receive addresses.

A 2kb size was chosen to preserve the flexible use of the receive address field, where it's just a string and can be interpreted by various modules to trigger other functionality.

TODO:

• use error conventionally
• write a test
