Keep Core load unchanged in the iOS charger display

[frahlg]

The iOS charger display could subtract charger watts from Core’s qualified house load, or create a false 0 W when Core omitted load. That also reached Watch through NowFlow. The app now leaves Core load unchanged while adding an EV display reading. An absent or null load stays unknown, a known zero stays zero, and the home remains visible with no reading.

Paired Core PR: srcfl/ftw#1733 (reviewed source head 4daab0799ead10d9abdbf4ab66bdbe7d476ca6bb). Core uses one qualified live-load calculation for local status, app snapshots and FTW Cloud. It changes no wire field or registry name. withLoadpointEV keeps its signature; the legacy Readings.loadKw is now optional so that API can represent missing load. Current app/widget/Watch targets compile with it.

Validation:

• Four new regressions fail on unchanged main with 17 assertion issues, then pass after the fix. They cover absent/zero/fractional load with charger fallback, missing/null HTTP load, Now, and Watch.
• Full Swift checks: 266 shared tests and 551 kit tests pass.
• Native iOS Simulator app, widget and Watch build passes. Remote Apple CI run 39145749162 also passes its package tests, native targets and normal demo photographs. The CI photographs show the ordinary demo. A separate local native UI test also passes: after a known 1.6 kW reading, a full snapshot omits FID6 and both Now and the detail view show unknown; another run shows known Load=0 as 0 W. Its five screenshots and result bundle are saved for review. Only the demo/test fixture changed for this render; that patch is saved outside the PR and the worktree is restored to the submitted head.
• Android shared JVM checks pass on JDK 21: 44 tests, no failures or errors, one intentional skip.

This PR contains no timeline redesign; that remains draft #93. It does not publish or install an iOS beta, and Hannes’s exact installed app build remains unknown. The fix has not been verified on a physical iPhone or Watch.
