Unify jQuery: serve public site jQuery via asset pipeline

Remove vendored jquery-1.3.2.min.js, jquery-ui-1.7.2.custom.min.js,
and the unreferenced duplicate jquery.hotkeys.js from public/javascripts/.

Public layout now loads jQuery via a small public_bundle.js manifest
through the asset pipeline, same mechanism already used for the admin
interface (admin_bundle.js). This brings the public site from jQuery
1.3.2 (2009) to the current jquery-rails-provided version (3.7.x).

Shadowbox's jQuery adapter (shadowbox-jquery.js) only uses stable APIs
(.css, .remove, .bind, .unbind, .append, .extend) unchanged across this
version span. Verified by manual click-test: gallery image opens,
displays, and dismisses correctly.

public.js required no changes — all jQuery APIs used
(.ready, .bind, .trigger, .length) are stable across versions.
