fix: limit chart data to last 90 days

[graphieros]

This limits the chart dataset to the last 90 days, to avoid long streaks of empty days when a set contains a very old date.

Before	After

Summary by CodeRabbit

• New Features
  • Account events timeline now shows only the most recent 90 days of activity.
  • Timeline labels and chart data use hourly granularity within that 90-day window for clearer recent activity trends.
  • Events are filtered to active event types so the chart focuses on relevant activity.

📝 Walkthrough

Walkthrough

AccountEventsTimeline now computes a UTC-based 90-day rolling window (dayRangeLimit = 90) from qualifying GitHub events, filters events to that window (limitedEvents), and uses limitedEvents for hourly time labels and building the per-event chart dataset via a constant activeGitHubEventTypes list.

Changes

Event days rolling window & dataset

Layer / File(s)	Summary
Compute rolling 90-day window and limitedEvents app/components/Chart/AccountEventsTimeline.vue	Adds dayRangeLimit = 90, defines activeGitHubEventTypes and isActiveGitHubEventType, rewrites eventDays to a UTC rolling window ending on the latest qualifying event day, derives limitedEvents from that window, and removes the old computed activeGitHubEventTypes.
Hourly labels and dataset from limitedEvents app/components/Chart/AccountEventsTimeline.vue	Changes timeLabels to use limitedEvents for the complete hour range, iterates the constant activeGitHubEventTypes when building per-event series in createLineDataset, and computes datasetLine from limitedEvents.value.

Poem

🐰 I counted days in ninety-wide bands,
Rolled them up neat with careful hands,
Events trimmed to a recent parade,
Hours aligned from the window we made,
Charts hop lighter — rabbit-approved plans.

In `@app/components/Chart/AccountEventsTimeline.vue`:
- Around line 98-113: The hourly labels are still generated from all events by
getCompleteHourRange(props.events), bypassing the 90-day/eventDays window;
update the hourly-label generation to use the same filtered range: either pass
the computed startDay/lastDay (from the eventDays computation that derives
startDay) into getCompleteHourRange or, after calling getCompleteHourRange,
filter its returned hours to only include timestamps between startDay
(inclusive) and lastDay (inclusive). Reference the computed that builds
days/startDay (lines with variables days, lastDay, startDate, startDay) and
getCompleteHourRange so the hourly mode cannot expand beyond the same
constrained eventDays.
