Fix safe_return_to being uncallable from controllers

Defined only in ApplicationHelper, which Rails auto-mixes into views
but not controllers - so events#create and events#update, which call
it directly, have been broken since introduction. Likely unexercised
until now because every existing event was created via
node.events.create! in the seed script, never through a real POST.

Moved to ApplicationController as a protected method + helper_method
declaration, so both controllers and views can call it (form_error_
messages stays in ApplicationHelper - it's genuinely view-only,
content_tag isn't available in a controller either). Logic unchanged,
caught by the new EventsController tests in the previous commit.
