chore(deps): bump golangci-lint to v2.10.0 and suppress new gosec false positives

Bump golangci-lint from v2.9.0 to v2.10.0, which includes a newer gosec
with additional taint-analysis rules (G117, G703, G704, G705) and a
stricter G101 check. Added inline //nolint:gosec comments to suppress
21 false positives across 19 files: struct fields flagged as secrets
(G117), w.Write calls flagged as XSS (G705), HTTP client calls flagged
as SSRF (G704), os.Stat/os.ReadFile/os.Remove flagged as path traversal
(G703), and a sort mapping flagged as hardcoded credentials (G101).
