Update tool dependencies and fix new lint issues (#36702)

## Summary - Update golangci-lint v2.9.0 → v2.10.1, misspell v0.7.0 → v0.8.0, actionlint v1.7.10 → v1.7.11 - Fix 20 new QF1012 staticcheck findings by using `fmt.Fprintf` instead of `WriteString(fmt.Sprintf(...))` - Fix SA1019: replace deprecated `ecdsa.PublicKey` field access with `PublicKey.Bytes()` for JWK encoding, with SEC 1 validation and curve derived from signing algorithm - Add unit test for `ToJWK()` covering P-256, P-384, and P-521 curves, also verifying correct coordinate padding per RFC 7518 - Remove dead staticcheck linter exclusion for "argument x is overwritten before first use" ## Test plan - [x] `make lint-go` passes with 0 issues - [x] `go test ./services/oauth2_provider/ -run TestECDSASigningKeyToJWK` passes for all curves 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>
