DiscordNewSessionHandler.ParseTimeInput used DateTimeStyles.AssumeUniversal,
which interpreted user input as UTC. A user entering 15:00 got a session
scheduled at 18:00 MSK after rendering. Align with Telegram behavior by
treating input as Moscow time and converting to UTC before storage.

- DiscordPermissionChecker: removed dead-code userRoles overload;
now only uses resolvedPermissions bitflag (Administrator = 0x8).
- DiscordNewSessionCommand: computes resolved permissions from guild
user roles via Context.Guild.Users[Id].RoleIds + guild.Roles.
- DiscordNewSessionHandler: updated signature to accept ulong
resolvedPermissions instead of unused userRoles.
- Added ILogger to command for diagnostics on unexpected errors.
- Added test: regular user with ManageServer (but not Admin) is rejected.
