fix: trigger score pipeline after health sync for recent dates with no prior backend summary

[Copilot]

When the app hasn't been opened for multiple days, recent dates (within 14 days) with HealthKit data but no backend summary never get scored — blocking recommendations from appearing.

Root cause

triggerOnDemandPipelinesIfNeeded is called before syncRecentDateIfNeeded in HomeSummaryStore.load(). When the backend has no entry for a date, resolvedSummary is nil, and the function exits early:

guard let summary else { return .none }  // fires when backend has no summary yet

Health data is then uploaded by syncRecentDateIfNeeded, but the score pipeline is never triggered — so the backend has data but never computes a score.

Fix

After syncRecentDateIfNeeded uploads health data and the summary is refreshed, trigger the score pipeline if:

• it wasn't already triggered before the sync (!onDemandTriggerResult.attemptedScore)
• a summary is now available (resolvedSummary != nil)

if !onDemandTriggerResult.attemptedScore, resolvedSummary != nil {
    let postSyncTriggerResult = await triggerOnDemandPipelinesIfNeeded(
        using: authManager,
        for: selectedDate,
        summary: resolvedSummary
    )
    if postSyncTriggerResult.attemptedAny {
        // invalidate cache and refresh summary
    }
}

This preserves existing behavior for dates where a summary was already present (pipeline triggered before sync, attemptedScore == true) and correctly handles the case where health data needed uploading first.
