WOOA7S-1769: Premium Analytics: Remove the plan usage widget

[Nikschavan]

Part of WOOA7S-1769

Stacked on #53357, so this PR targets that branch. Please review and merge it after #53357.

Proposed changes

• The plan usage widget (jpa/plan-usage) was held back on every site, and WOOA7S-1769: Premium Analytics: Add a Settings tab to the dashboard #53357 moves plan usage to the dashboard's Settings tab, so the widget no longer has a place to show. WOOA7S-1769: Premium Analytics: Add a Settings tab to the dashboard #53357 had moved its helpers into widgets-toolkit and exported them so the widget and the Settings card could share them, which added three public names (getOverLimitMessage, getPlanUpgradeUrl, usePlanUsage) for one real caller.
• Remove the widget, its story and its Storybook mock, and drop the server-side hold that kept it out of the widget list. The helpers move next to the Settings card and are no longer exported, so the widgets-toolkit API is back to what trunk has.
• Delete the widget's tests too. The rules they covered are tested on the Settings card in WOOA7S-1769: Premium Analytics: Add a Settings tab to the dashboard #53357, which renders the same usage data.

Nothing changes for site owners: the widget was never registered on any site, so a saved layout that still holds a jpa/plan-usage instance behaves as it does today.

Testing instructions

Use a site with Jetpack and Premium Analytics from this branch (Jetpack Beta Tester pointed at wooa7s-1769-remove-plan-usage-widget), connected, with Stats on, and log in as an administrator.

• Go to Stats v2 › Settings. "Your current plan" still shows the views used against the limit, when the cycle restarts and Upgrade.
• Open Page options › Customize on Traffic and open the widget inserter. There is no plan usage widget, the same as on trunk.

I ran the Premium Analytics JS and PHP suites locally. I did not check this branch in a browser.
