Fix AttributeError: 'Channel' object has no attribute 'info' (#326)

[CoderBoxer]

Overview

Fixes an AttributeError crash that occurs when attempting to play or favorite streams from Xtream providers.

Changes

• Refactored the string construction inside both before_play and on_favorite_button_toggled.
• Replaced direct .info access with getattr(channel, 'info', '') (or self.active_channel).
• This defensively handles Xtream Channel objects that lack the .info property, preventing a hard crash while safely preserving the data and ::: string formatting for standard M3U channels that still rely on it.

Closes #326

I can confirm that this issue also affects Favorites with Xtream providers in Hypnotix 5.6-2.

When clicking the Favorites button, on_favorite_button_toggled() accesses self.active_channel.info, but the Xtream Channel class does not have an info attribute. After removing the early page_is_loading return, this results in:

AttributeError: 'Channel' object has no attribute 'info'

I tested a local fix that handles Xtream channels separately and stores them in the existing EXTINF-based Favorites format. With this change, the channel is saved to ~/.cache/hypnotix/favorites/list, appears in Favorites, and can be played normally.

So I can confirm that the issue addressed by this PR affects Xtream Favorites as well.
