- New Cost_Tracker class: logs every API call (model, tokens, cost), enforces
monthly budgets with hard-stop mode, provides aggregated reporting
- New llm_costs database table with indexes on created_at, model, operation
- Modified LLM class: call_openrouter_with_usage() extracts token usage from
OpenRouter responses; budget gate checks before each API call
- Admin settings: monthly budget (USD), enforcement mode (disabled/warn/hard-stop),
cost log retention period
- Admin cost dashboard: budget progress bar, daily cost chart (Chart.js),
per-model and per-operation breakdowns, recent API call log
- PHPUnit tests: 16 tests covering cost calculation, pricing lookups,
budget enforcement logic, and model validation
- Updated ARCHITECTURE.md with new table schema, data flow, and key decisions
- Updated CONVENTIONS.md with "how to add cost tracking for a new operation"
- Version bump to 2.4.0

Chart.js with responsive:true + maintainAspectRatio:false requires
the parent container to have an explicit height. Without it, charts
grow unbounded. The prepareCanvas() helper wraps each canvas in a
height-constrained div before Chart initialization.

Charts were not rendering properly because admin-script.js targeted a
non-existent canvas ID (peptide-analytics-chart) instead of the actual
IDs (pn-trends-chart, pn-devices-chart, pn-sources-chart). The script
also used hardcoded demo data instead of the peptideNewsDashboardData
object exported from PHP.
Changes:
- Rewrite admin-script.js to initialise all three dashboard charts
(line, doughnut, bar) using the correct canvas IDs and PHP data
- Set maintainAspectRatio: false so explicit canvas heights are respected
- Add max-height CSS constraint on chart canvases to prevent unbounded
vertical growth
- Sync JS/CSS to admin/ root directory to match PEPTIDE_NEWS_PLUGIN_URL
asset path
