feat(bindings): tnumber × {numspan, tbox} bounding-box predicates (topo + position)

[estebanzimanyi]

Summary

Combines topological (@>, <@, &&, -|-) and position (<<, >>, &<, &>) predicates between tnumber and numspan/tbox, plus tnumber × tnumber variants. 136 ScalarFunction registrations total (96 topological + 40 position).

This PR consolidates two previously stacked PRs covering the same bounding-box surface across the same templated helpers (TempBoxBoolPred<Span|TBox> / BoxTempBoolPred<Span|TBox> / TempTempBoolPred).

Coverage

Op set	tnumber × numspan	numspan × tnumber	tnumber × tbox	tbox × tnumber	tnumber × tnumber
Topo (@>, <@, &&, `-	-`)	✓	✓	✓	✓
Position (<<, >>, &<, &>)	✓	✓	✓	✓	✓

tint and tfloat cover the tnumber surface; intspan/floatspan for the numspan surface.

Test plan

• All 136 registrations load
• Smoke tests for representative entries in each cell of the table
• Full local suite passes net of pre-existing TZ-environment failures

Replaces

• feat(bindings): tnumber × {numspan, tbox} topological predicates #37 (topological)
• feat(bindings): tnumber position predicates (<<, >>, &<, &>) #38 (position)
