refactor: attempt rework for pre-component / pre-command checks

[sudojunior]

// current
if (condition) {
  // run code
}

// proposed
try {
  check(condition, failReason);
} catch (error) {
  await ctx.send(error?.message || error);
  return;
}

Approach to testing condition is derived from test framework assertions assert(condition, reason).

Currently used for the setup wizard when checking for channel permissions.
