Fix release schedule percentages and miner fee estimate in Avalonia invest view

[Copilot]

Two display bugs in the Avalonia investor flow: stage release percentages rendered as 1000%/3000% instead of 10%/30%, and miner fee always showed 0.

Percentage fix — DocumentProjectService.cs

AmountToRelease is stored as a whole percentage (e.g. 10 = 10%). ProjectService already divided by 100 when mapping to RatioOfTotal; DocumentProjectService did not, so the p0 StringFormat (×100) produced 1000%:

// Before
RatioOfTotal = stage.AmountToRelease

// After
RatioOfTotal = stage.AmountToRelease / 100m

Miner fee estimate — InvestViewModel.cs

GetTransactionDetails hardcoded new AmountUI(0) for miner fee. It now estimates based on transaction virtual size (overhead + 1 P2WPKH input + stage outputs + change) at 1 sat/vbyte, using the stage count from the selected pattern (Fund/Subscribe) or static project stages (Invest):

int estimatedVSize = txOverhead + inputSize + (stageCount + 2) * outputSize;
long minerFeeSats = estimatedVSize * defaultFeeRateSatsPerVByte;

Details is also combined with SelectedPattern so the estimate updates reactively when the user switches funding patterns.
