Default channel when replying

Currently, if a user is subscribed to a ticket in an inbox they don't have direct access to (e.g., in their "Shared with me" section), and they go to reply, the default "From" address is not the channel associated with that specific inbox. Instead, it defaults to another channel they may have access to, such as their primary inbox or shared channels in alphabetical order. While the user can manually change the "From" address to the correct channel, this extra step often gets overlooked.

The request is to have Front automatically default the "From" channel to the inbox from which the original message was received, regardless of whether the user has full access to that inbox. This would significantly reduce user error and streamline workflows, particularly for team members who interact with conversations across various departments without needing full access to every inbox. The current functionality already allows manual selection of the correct "From" address in these scenarios, so the core capability exists.

This enhancement would improve efficiency and ensure consistent communication by making the "From" field automatically align with the context of the conversation.
