Compose Transaction: Option to auto-fill sender address to connected wallet addresss

[No-Cash-7970]

Is your feature request related to a problem? Please describe.

When composing a transaction, there is no easy way to enter the sender address, (required for every transaction) besides copying and pasting it from somewhere.

Describe the solution you'd like

When a wallet is connected to an account, the sender address in the "Compose Transaction" form should be auto-filled. This feature should be able to be easily turned off by using a "Use connected wallet address" checkbox below the sender address field. Whether the "Use connected wallet address" checkbox is checked by default when composing a new transaction should be an option in the settings. That option in the settings should be "on" by default.
