fix(console): correct usage chart labels from functions/sites to deployments

[singhvishalkr]

Summary

Fixes #2224

The usage chart on both the Functions and Sites aggregate usage pages displays incorrect labels. The data source is deploymentsTotal / deployments, but the chart metadata says "Total functions" / "Total sites" respectively.

Changes

• Functions usage page: Changed legend from "Functions" to "Deployments" and title from "Total functions" to "Total deployments"
• Sites usage page: Changed legend from "Sites" to "Deployments" and title from "Total sites" to "Total deployments"

Both pages load deployment metrics from the API (data.deploymentsTotal, data.deployments), so the labels should reflect that.

Files changed

• src/routes/(console)/project-[region]-[project]/functions/usage/[[period]]/+page.svelte
• src/routes/(console)/project-[region]-[project]/sites/usage/[[period]]/+page.svelte

Test plan

• Navigate to Functions > Usage tab and verify chart says "Total deployments"
• Navigate to Sites > Usage tab and verify chart says "Total deployments"
• Verify the actual count matches the number of deployments, not the number of functions/sites

Greptile Summary

This PR fixes a label mismatch in the usage charts for the Functions and Sites pages: the chart metadata previously displayed "Total functions" / "Total sites" even though both pages source their data from deploymentsTotal and deployments. The fix updates legend and title to "Deployments" / "Total deployments" in both components.

Confidence Score: 5/5

Safe to merge — two-line label-only changes with no logic impact.

The changes are purely cosmetic string corrections that align chart labels with the actual data source already in use. No logic, data flow, or security concerns introduced.

No files require special attention.
