fix(projects): isolate quote acceptance status per project (decision-target based)

Bug: a multi-project quote accepted for «تست ۱» only also appeared under «تست ۲»'s پذیرفته شده column, because both the Projects page and /projects/{id}/stats classified quotes by their GLOBAL status over any project link.

Rule now: a quote counts as accepted/arrived for a project ONLY if at least one non-rejected line item's decision targets that project (item_decisions.project_id). A quote merely linked as a candidate — including one accepted for a different project — is categorized exclusively under پیشنهاد شده for that project. Legacy quotes without any decision targets keep the old global-status classification.

Backend: project_stats membership now spans all link kinds (legacy mirror, quote_projects, line_item_projects, decision targets) with the per-project decision-based bucketing above; bucket VALUES follow the same isolation (accepted/arrived value counts only items targeting the project; candidate items of a still-proposal quote stay in the offered bucket); the raw path string is normalized to UUID for the Python-side comparisons. /quotes?project_id=… now matches any relevant link kind instead of only the legacy mirror column.

Frontend: ProjectsPage gains acceptedForProject/hasTargets helpers; the three columns (پیشنهاد شده / پذیرفته شده / رسیده) and their value chips use per-project items (target-project items first, then candidates), so totals no longer leak other projects' items.

Verified end-to-end (2 projects × 1 quote × 2 items, accept item-1 for P1 only): P1 accepted=1 then arrived=1 after the PM receipt; P2 stays offered=1 / accepted=0 / arrived=0 at every step; /quotes?project_id=P2 still lists the quote. All fixture data removed; 7/7 checks pass. python compile + api/frontend builds clean.
