Ollama monthly usage limit is not displayed

[kshitijpatil]

Description

OpenUsage detects my Ollama account correctly and shows the Free plan and recent activity cost, but it does not display the monthly usage limit returned by Ollama.

The Ollama usage API currently returns a monthly usage value under:
limits.monthly.usage

For example:
limits.monthly.usage = 0.053
which represents 5.3% monthly usage.

Authentication appears to be working correctly. OpenUsage detects the Ollama account and plan, and the Ollama /api/usage endpoint returns the usage data successfully when authenticated.

Steps to Reproduce

1. Sign in to Ollama using ollama signin.
2. Enable the Ollama provider in OpenUsage.
3. Verify that https://ollama.com/api/usage returns limits.monthly.usage.
4. Check OpenUsage's local API using:
   curl -s http://127.0.0.1:6736/v1/usage | jq
5. Observe the Ollama provider output.

OpenUsage currently returns an Ollama entry containing the Free plan and a "Last 4 Weeks" cost line, but no monthly usage progress line.

Expected Behavior

OpenUsage should parse limits.monthly.usage and display it as a monthly usage progress indicator.

For example:
Monthly: 5.3%

Actual Behavior

OpenUsage detects the Ollama account and plan and displays recent activity cost, but the limits.monthly.usage value is not displayed.

The UI currently only shows something similar to:
Plan: Free
Last 4 Weeks: $0.00

No monthly usage progress is shown.

I can reproduce this from the code. On main (56378e5), OllamaUsageMapper.usageLines builds meters only from limits["session"] and limits["weekly"], so the limits.monthly entry is never read. The fix would be a third percentLine(limits["monthly"], label: "Monthly") in the same pattern, plus a mapper test with a monthly payload. Since percentLine returns nil when an entry is missing, accounts without a monthly limit keep today's output.

I'd like to pick this up if it gets approved. Could you assign it to me?
