feat: chart grid, pressure tolerance bands, QDelivery RPM normalization, pump page polish

Charts
- Add faint background grid (0.75px, #E0E0E0) to all live charts; matches PDF report style
- Show min/max tolerance bands on P1/P2 pressure charts during test runs (previously only Q-Delivery/Q-Over)
- Broaden BenchService.ToleranceUpdated to fire for every phase receive; UI routes by name
- Clear P1/P2 traces on PhaseChanged alongside Delivery/Over

CAN
- Normalize QDelivery flow rate to 1000 RPM reference before IIR filter so RPM spikes are low-pass filtered with flow-rate transients (matches old_source behavior)

Pump page
- Reorder columns: identification left, commands center, live data right
- PreIn control always visible; disabled when pump lacks pre-injection (rename IsPreInVisible -> IsPreInAvailable)
- Swap value/label order in command cards
- Remove redundant KlineErrors row from identification card
