The value types and compose helpers in Federation.h were already Qt-free —
Eigen and std::string — but sat in the Qt half of the viewer, so the web build
could not reach them. Split them into FederationMath and add it to
IfcViewerCore, which the Emscripten build links.
What stays behind is what genuinely needs the dependencies: computeModelGeoref
reads an ifcopenshell::file, and the Federation class is a QObject that
persists .ifcfed. Federation.h includes the new header, so no caller changes.
FederationMath needs convert() to resolve a federation unit name to metres and
x_axis_to_angle_deg() to read grid north off a coordinate operation, hence the
helpers_math dependency added in the previous commit.

unit.h and geolocation.h both include ../ifcparse/express.h for the entity
walking they do, which puts the whole module out of reach of anything that
cannot link IfcParse. Most of what a viewer wants from them needs no IFC at
all: the unit conversion tables, and the Helmert parameters-to-matrix math.
Move those into unit_convert and geolocation_transform, and build them as a
new helpers_math target that `helpers` re-exports PUBLIC, so existing callers
keep working through the unchanged unit.h / geolocation.h includes. The new
target has no IfcParse or Qt dependency and so builds under Emscripten, where
the rest of this directory cannot.
One target rather than compiling the sources into each consumer: the glob in
this directory would otherwise put them in libhelpers.a as well, leaving two
copies of the same objects in any link that pulls both.

Queued chunk loads waited for the next render frame to start, so streaming
advanced at frame cadence rather than as fast as the in-flight cap allowed.
driveStreamingLoads now queues whatever it could not start and every load
completion drains that queue, decoupling fetching from the render loop.
pumpWebChunkLoads is deliberately defined outside the __EMSCRIPTEN__ block
that holds the rest of the byte-range streaming code: driveStreamingLoads
calls it unconditionally and ViewportCore.h declares it unconditionally, so
desktop needs a definition to link against. The body guards itself instead
and compiles to a no-op off the web, where loads are not asynchronous.

Most of them are actually correct, but they're not enforced in general on the repo, so using them blocks us from flagging `unused-noqa` for rules that we actually do use.
An SI prefix attaches to the base unit symbol and the prefixed symbol is
raised to the power as a whole: DECI CUBIC_METRE is dm3 = a litre = 1e-3 m3,
not 0.1 m3. The scale factor previously applied the prefix multiplier
linearly for all IfcSIUnits, inflating volumes x100 and areas x10 for such
declarations (produced e.g. by MagiCAD for Revit MEP exports).
Following the reviewer note in #9278, the exponent is taken from the
derived attribute IfcSIUnit.Dimensions rather than from substring matching
on the unit name: the multiplier is raised to LengthExponent only when the
unit's dimensions are a pure power of length, so prefixed derived units
(KILO PASCAL, MEGA NEWTON) and non-length units (KILO GRAM) correctly keep
the linear multiplier. This matches the exponent handling already present
in convert() and named_dimensions in the same module.
Adds regression tests for prefixed AREAUNIT/VOLUMEUNIT and for the
linear-prefix behaviour of PRESSUREUNIT/MASSUNIT.
