Fix editor interaction, loading, and IFC cleanup

[wass08]

Summary

• Fix site label sizing after camera swaps, including orthographic mode.
• Improve viewer loading gates so reloads and project switches keep the spinner visible until the scene is ready.
• Add WASD camera panning, move delete mode to X, and add the floorplan north compass.
• Progressively rebuild large wall, door, and window batches so dense scenes stay responsive while they build.
• Simplify noisy IFC converter output by merging collinear wall fragments, rehosting openings onto merged walls, pruning tiny walls, and deduping repeated doors/windows.

Test plan

• bun check
• bun check-types
• bun test packages/ifc-converter/tests/cleanup.test.ts
• bun --filter @pascal-app/ifc-converter build
• Manual: large IFC conversion scene loads without freezing in the community app before the converter cleanup pass; converter simplification is covered by focused unit tests.

Notes

• A terminal conversion smoke against bundled IFC files is currently blocked because web-ifc looks for /web-ifc-node.wasm outside the app-server WASM setup.
