Fix Leave option not shown when Delete option is visible for group channels

[VelikovPetar]

Goal

For group channels where the current user has both leave-channel and delete-channel capabilities (typically channel owners/admins), the channel info screen and the Compose channel-list options menu were only surfacing Delete and hiding Leave. Users want to be able to leave a group they own without having to delete it for everyone.

This change makes both options available whenever the user has the corresponding capability.

Implementation

• ChannelInfoViewController.buildChannelOptionList: appends LeaveChannel whenever leave-channel capability is present, and independently appends DeleteChannel when delete-channel is present (previously the two were mutually exclusive via if/else).
• ChannelOptions.buildGroupChannelActions (Compose channel-list bottom sheet): shows LeaveGroup whenever canLeaveChannel, dropping the && !canDeleteChannel exclusion.
• ChannelInfoOptionButton: replaces the CompositionLocalProvider(LocalContentColor = accentError) wrapper with an explicit destructive: Boolean parameter that drives icon tint and text color (buttonDestructiveText vs textSecondary/textPrimary). Call sites for BlockUser, LeaveChannel, and DeleteChannel pass the appropriate flag — LeaveChannel and DeleteChannel are destructive, BlockUser is not.
• ChannelInfoViewControllerTest: existing owner-capabilities test updated to expect both LeaveChannel and DeleteChannel in the option list.
• Snapshot images regenerated for ChannelInfoOptionItemTest (direct + group, light + dark) and DirectChannelInfoContentTest to reflect the explicit destructive coloring.

Testing

• Updated unit test in ChannelInfoViewControllerTest covers the owner case (both capabilities → both options listed).
• Updated snapshot tests cover the destructive coloring in light/dark mode for both direct and group channel option items.
• Manual verification: open a group where you have both leave and delete capabilities and confirm both options appear in the channel info screen and in the Compose channel-list long-press menu.
