feat: phase 4 - reminders, post-study feedback, grade trends, weekly planner

[timh8127]

Summary

Implements all four Phase 4 features from wsist-phase4-tasks.md:

1. Missing grade reminders — home page strip listing past tests with no grade entered; clicking a chip opens the edit modal for that test.
2. Post-study understanding update — each study card gets a "Studied it" button with an inline prompt to update understanding; recommendations re-run immediately so scores reflect the change.
3. Grade trend chart — per-subject SVG sparklines (pure Razor-rendered SVG, no JS chart libraries) for subjects with 2+ graded tests, with guide lines at grades 4/5 and a first-to-latest delta.
4. Weekly study planner — Today/This-week toggle on the study page; enter available hours per day and get a 7-day plan driven by PriorityCalculator.GetWeeklyPlan.

Notes

• Added @using WSIST.Engine to Study.razor (required by the new markup referencing Test enums).
• Added GetGradeClass to Study.razor.cs (weekly plan rows use it; it previously existed only on Home).
• No migrations; dotnet build ran clean (0 errors) before each commit.

📝 Walkthrough

Walkthrough

Adds date-anchored scoring and a 7-day weekly planner to PriorityCalculator; Home shows missing-grade reminders and SVG grade trends; Study page gains Today/This-week modes, studied-test feedback, per-day hour inputs, and a weekly plan view powered by the new planner.

Changes

Study Planning and Grade Tracking

Layer / File(s)	Summary
Weekly Plan Calculator WSIST/WSIST.Engine/PriorityCalculator.cs	Threaded optional asOfDate through scoring APIs; CalculateUrgencyScore uses asOfDate for due-date math; CalculateTotalScore and GetStudyRecommendations accept asOfDate; new GetWeeklyPlan returns a 7-day Dictionary<DateOnly, List<Test>> using hoursPerDay to decide per-day recommendations or empty lists.
Home Page – Grade History and Missing Tests WSIST/WSIST.Web/Components/Pages/Home.razor.cs, WSIST/WSIST.Web/Components/Pages/Home.razor, WSIST/WSIST.Web/wwwroot/app.css	Adds MissingGrades (overdue tests with unset Grade) and GetGradeHistory() (per-subject chronological graded tuples for subjects with ≥2 grades). Home renders a missing-grade strip with Edit actions and a Grade trends SVG card (polyline + markers, guide lines, count/delta footer). Styles for chips and trend cards added.
Study Component – Imports, Toggle, and State WSIST/WSIST.Web/Components/Pages/Study.razor, WSIST/WSIST.Web/Components/Pages/Study.razor.cs	Adds @using WSIST.Engine, a study-mode toggle (Today vs This week), and state for studied-test editing and weekly planning (studiedTestId, updatedUnderstanding, weeklyMode, weeklyHours, weeklyPlan, weeklyCalculated).
Study Component – Studied Test and Weekly Planning Workflows WSIST/WSIST.Web/Components/Pages/Study.razor, WSIST/WSIST.Web/Components/Pages/Study.razor.cs, WSIST/WSIST.Web/wwwroot/app.css	Today mode: recommendation cards show a studied-test prompt (understanding select + Save/Cancel) or “✓ Studied it” opener. This week mode: per-day hours inputs, CalculateWeekly() calling PriorityCalculator.GetWeeklyPlan, and a weekly plan display listing each day’s tests with scores and “days away” text. Includes studied-prompt handlers (OpenStudiedPrompt, CancelStudiedPrompt, SaveStudiedUnderstanding), helpers (DayLabel, GetGradeClass), and related CSS for post-study feedback and the weekly planner.

Poem

🐇 I hop from card to chart and plan,
Seven days sorted by a careful scan,
Remind the missing, trace the trend line,
Save how you learned — one test at a time! 🎓

In `@WSIST/WSIST.Engine/PriorityCalculator.cs`:
- Around line 96-110: GetWeeklyPlan builds the 7-day plan using
GetStudyRecommendations but GetStudyRecommendations currently uses
DateTime.Today as its reference (causing tests to be considered relative to
today rather than each iterated date), so change GetStudyRecommendations to
accept a reference date parameter (e.g., DateOnly referenceDate) and update its
internal filtering/scoring to use that referenceDate instead of DateTime.Today;
then call GetStudyRecommendations(allTests, hours, date) from GetWeeklyPlan
(where date is the loop variable) so each day's recommendations are computed
relative to that day.

In `@WSIST/WSIST.Web/Components/Pages/Study.razor.cs`:
- Around line 75-90: After reloading allTests in SaveStudiedUnderstanding,
invalidate or recompute the weeklyPlan so the UI doesn't show stale weekly rows:
after allTests = management.LoadAllTests(CurrentUserId) call the existing weekly
planner recompute (e.g. weeklyPlan = weeklyPlanner.CalculateWeeklyPlan(allTests,
/*hours/dates*/ ) or set weeklyPlan = null and invoke the method that builds it
(or call RecalculateWeeklyPlan()) so weeklyPlan reflects the updated data before
StateHasChanged(); reference SaveStudiedUnderstanding, management.TestEditor,
LoadAllTests, weeklyPlan, and StateHasChanged in the change.
