Normalize action-button wording and add icons app-wide

"New X" becomes "Create X" throughout (users, events, assets, menu
items, nodes), matching the verb-first pattern the dashboard's own
signposts already established, with a shared plus icon rather than a
document-flavored one that only made sense next to "post". The
"Destroy"/"destroy"/"Delete" family is normalized to "Destroy"
everywhere, with a shared trash icon; occurrences#index and
pages#index also pick up the destructive button class they'd been
silently missing. Filter and Search convert from submit_tag to
button_tag, the only way either can hold an icon alongside its label.

Edit and the node editor's three dynamic labels (Continue Editing /
Edit Draft / Lock + Edit) share one icon without touching their
wording -- unlike Destroy's family, the state nuance in the text is
real information, not just inconsistent phrasing.
