fix: weekly goal and monthly stats update

[akeight]

Summary

Fixes several dashboard stat calculations that were counting the wrong applications or not updating live.

• Applied stat card: no longer includes saved/other statuses. The card now uses the APPLIED count instead of the all-status total, so it reflects only actual applications.
• Weekly Goal + Applications Submitted chart: exclude SAVED applications. Added SUBMITTED_STATUSES in src/lib/status.ts; the profile stats query and the chart now filter out saved rows (APPLIED, INTERVIEW, OFFER, REJECTED still count).
• Weekly Goal date basis: computeStreak now buckets weeks by appliedAt (when you applied) instead of createdAt (when the row was added). This keeps the Weekly Goal consistent with the Applications Submitted chart and correctly credits the week a saved job is actually applied to.
• Live updates: added profile.get cache invalidation to every application create/edit/status-change/delete mutation, so the Weekly Goal ring refreshes immediately like the other charts instead of requiring a page reload.

Test plan

• Dashboard: with saved + applied internships, the Applied card shows only applied count (not saved).
• Weekly Goal and Applications Submitted chart exclude saved items and agree on counts.
• Add an application with Applied status: Weekly Goal updates without a page refresh.
• Move an item to/from Applied (kanban), edit, and delete: Weekly Goal updates live.
• Demo sandbox: numbers are consistent (Weekly Goal reflects applications by applied date, ~1/week).
