Remove jQuery UI: replace datepicker with air-datepicker, drop tooltips

jQuery UI was vendored in two locations (~250KB of JS+CSS+images) but
only two of its widgets were actually used:

- .datepicker() in two report-param JSPs — replaced with air-datepicker v2
  (already vendored at javascript/air-datepicker/, never wired up before).
  Same jQuery-plugin call shape ($("#x").datepicker({...})). Cross-field
  min/maxDate constraint is now wired via onSelect callbacks.

- .tooltip() — global init in transitime.js plus per-page wirings on
  Select2 containers in 8 form-param JSPs. Dropped entirely; native
  browser tooltips on the underlying <input>/<select> remain. The two
  "tooltip-disable" workarounds in maps/map.jsp and synoptic/index.jsp
  existed solely to suppress side effects of the global init and
  disappear with it.

Also:
- $('#mapTitle').hide('fade', 1000) — a jQuery UI effect — replaced
  with core jQuery $.fadeOut(1000).
- transitime.js now has a cache-buster query string, mirroring the
  existing pattern for general.css.
- <br>-based HTML in date/time tooltip title attrs converted to
  &#10; line-break entities so native browser tooltips render
  multi-line content correctly.

Deleted:
- transitclockWebapp/src/main/webapp/jquery-ui/ (full vendored library
  with 12 files including 10 PNG images, full CSS+JS, and a demo).
- transitclockWebapp/src/main/webapp/javascript/jquery-ui.{js,min.js}
  (duplicate vendored copy in the javascript/ dir).
