chore(viz): drop the legacy- prefix from migrated chart plugin packages

[rusackas]

SUMMARY

Phase 3 of #41714 (targets remove-legacy-viz-pipeline): with every chart in these packages on the v1 chart data API, the directories and npm names drop the legacy- prefix.

• legacy-plugin-chart-{calendar, chord, country-map, horizon, paired-t-test, parallel-coordinates, partition, rose, world-map} → plugin-chart-*
• legacy-preset-chart-nvd3 → preset-chart-nvd3 (Bullet and Time-series Period Pivot live on there; the other nvd3 charts were retargeted to ECharts)

References updated across package.json workspaces and the lockfile (which also carried stale entries for the long-gone legacy-preset-chart-deckgl), MainPreset imports, tsconfig path mappings + project references, webpack, the storybook-coverage script, custom-rule grandfather patterns (the renamed dirs keep their old color patterns/eager t() pending modernization), CODEOWNERS, dependabot config, docs, plugin READMEs, and story titles (out of the "Legacy Chart Plugins" group).

viz_type keys are untouched — no DB migration, saved charts are unaffected. Git tracks all moves as renames.

BEFORE/AFTER SCREENSHOTS OR ANIMATED GIF

N/A — package renames only.

TESTING INSTRUCTIONS

• npm install reconciles cleanly; zero legacy-plugin-chart/legacy-preset-chart references remain outside historical changelogs.
• npm run test -- plugins/plugin-chart-chord plugins/plugin-chart-world-map plugins/preset-chart-nvd3 plugins/plugin-chart-partition — 93 tests pass under the new paths.
• pre-commit run green.

ADDITIONAL INFORMATION

• Has associated issue:
• Required feature flags:
• Changes UI
• Includes DB Migration (follow approval process in SIP-59)
• Introduces new feature or API
• Removes existing feature or API
