[app] Wire JTSTestBuilder to use CurvedWKTReader / CurvedGeometryFactory

Phase 4-A of the SFA / ISO 19125-2 curve work (per discussion #1193).
Single-purpose change: every WKT-parsing path inside jts-app now uses
the curve-aware reader and factory, so curved WKT can be pasted, loaded,
saved, and round-tripped without any new UI.

What now works in JTSTestBuilder
- Pasting `CIRCULARSTRING(1 5, 6 2, 7 3)` (or COMPOUNDCURVE,
  CURVEPOLYGON, MULTICURVE, MULTISURFACE, TRIANGLE, POLYHEDRALSURFACE,
  TIN, with optional Z/M/ZM modifiers) into the Input A/B panels.
- Loading a `.jts` test case that contains curved WKT.
- Loading WKT/WKB files via File menu.
- The Geometry tree shows the correct type name (CircularString, etc.).
- Spatial functions fall through to the parent type's behaviour
  (polyline / polygon) per the phase-1 contract; explicit linearisation
  is available via Linearizable.toLinear(tolerance).

Files touched (all jts-app)
- pom.xml: add jts-curved dependency.
- testbuilder/JTSTestBuilder.java: fallback geometry factory is now
  CurvedGeometryFactory.
- testbuilder/model/TestBuilderModel.java: default geometry factory is
  CurvedGeometryFactory; loadGeometryText and the post-precision-model-
  change reload path use CurvedWKTReader / CurvedGeometryFactory.
- testbuilder/GeometryInputDialog.java: input parser uses the curved
  reader / factory.
- util/io/IOUtil.java: readWKTString uses CurvedWKTReader (this is the
  central WKT path, also reached via MultiFormatReader).
- util/io/MultiFormatBufferedReader.java: readWKT uses CurvedWKTReader.
- util/io/MultiFormatFileReader.java: readWKTFile uses CurvedWKTReader.
- test/TestCase.java: initGeometry and toNullOrGeometry use
  CurvedWKTReader / CurvedGeometryFactory for test-case WKT parsing.

What is intentionally NOT in this commit
- No drawing tools for curved geometries (defer to Phase 4-B).
- No CurvedShapeWriter / Bezier rendering (defer to Phase 4-B).
- No GeometryType enum extension or controller mode methods.

Net diff: +30 / -15 lines across 8 files. Reactor build is green
(jts-core 2288 + jts-curved 54 tests pass; all other modules unchanged).
