DINO-1164: add observability to new LAS on the rust server side & the main backend side (via @Timed) - #1067
All AI comments are fixed or resolved before requesting review
CI is green
Database changes follow the db repo rules, or this PR does not change the database. Comment /migrate to apply migrations to staging (Codebloom team only).
I QA'd this in dev and attached screenshots below. If staging could not be checked, say why.
Added metrics for credential refresh requests and outcomes, including their source, scheduled-check results, authentication-service latency by status, stored credential age, and refreshes in progress.
Documentation
Updated setup and integration guidance to describe the current LeetCode credential flow and removed outdated references to Playwright-based retrieval.
Expanded monitoring documentation to cover the available refresh, scheduled-check, latency, and credential-age metrics.
Deprecations
Marked the legacy authentication model and repository as deprecated.
Review was skipped as selected files did not have any reviewable changes.

Walkthrough
The Rust LeetCode authentication service now records refresh outcomes, request sources, scheduled-check results, LASS call latency, in-progress refreshes, and credential timestamps. Authentication documentation removes Playwright references. Legacy Java authentication declarations are deprecated, and the Java authentication service receives timing instrumentation.
Changes: LeetCode authentication updates
Layer / File(s)
Summary
Define and register service metrics internal/leetcode-auth-service/Cargo.toml, internal/leetcode-auth-service/src/observe.rs, internal/leetcode-auth-service/src/grpc/metrics.rs, internal/leetcode-auth-service/src/lib.rs, internal/leetcode-auth-service/src/main.rs, internal/leetcode-auth-service/README.md
Adds metric definitions and recording functions for refresh requests and outcomes, scheduled checks, in-progress refreshes, LASS call duration, and credential storage timestamps. Prometheus startup configures histogram buckets and describes the metrics.
Instrument refresh requests and scheduled checks internal/leetcode-auth-service/src/service/refresh.rs, internal/leetcode-auth-service/src/grpc/auth.rs, internal/leetcode-auth-service/src/config.rs
Refresh triggers now identify RPC or scheduled sources and record request, outcome, timing, and scheduled-check metrics. The RPC handler and tests pass an explicit source. TLS configuration parsing retains its false default for missing or invalid values.
Documentation removes Playwright credential-retrieval references. The legacy Java authentication model and repository are deprecated, and the Java authentication service receives Micrometer’s @Timed annotation.

Review details
Systems and components
observed — internal (service) was modified; 9 changed files map to changed impact.
observed — src (service) was modified; 4 changed files map to changed impact.
observed — example.env (service) was modified; 1 changed file maps to changed impact.
observed — exclusions.ts (service) was modified; 1 changed file maps to changed impact.
Before / after behavior
observed — Modified behavior in README.md: The backend description replaces Playwright and GitHub OAuth credential retrieval with credentials supplied by internal/leetcode-auth-service.
observed — Modified behavior in example.env: The SERVER_URL comment removes the statements that frontend URLs are loaded through Playwright and therefore need to go through the frontend.
observed — Modified behavior in exclusions.ts: Removed the PlaywrightProvider.java path from backendExclusions.
observed — Modified behavior in internal/leetcode-auth-service/README.md: The /metrics entry now documents refresh request totals and outcomes by source, local refreshes in progress, LASS request latency and buckets by gRPC status, scheduled-check results, and the last-seen stored-credentials timestamp and age calculation. The previous entry listed only gRPC request metrics and the refresh total.

Explanation
Docstring coverage is 10.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 10 functions across 11 files. (1 skipped: 1 unsupported.)
