feat(typescript) :: typecheck browser JavaScript in CI

[81reap]

Motivation

• The browser scripts carry JSDoc types that nothing checks, so a misspelt property or a missing null check only shows up in a browser.
• The browser tests are TypeScript, but nothing compiles them either. fix(modal) :: give modal component an accessible name #1367 fixed a getByRole option that does not exist; tsc reports it as TS2353.

Description

• Add a root tsconfig.json running checkJs and strict over sqlpage/*.js, and one per test project.
• Declare in sqlpage/globals.d.ts the names the bundle relies on at runtime rather than through an import: L, ApexCharts, chart_series, TomSelect, and tabler's bundled bootstrap.
• Declare in tests/end-to-end/globals.d.ts what the tests reach for on the page, chiefly the Tom Select instance sqlpage_select_dropdown attaches to a <select>.
• Fix what the checker found: unguarded page.goto() results in the tests, a querySelectorAll typed as Element, and an Array.prototype.shift whose result is only sometimes defined.
• Hoist @types/node to the root, add typescript, and run npm run typecheck from npm test.
• Split table sorting into three named tests, reading the cells as td._col_id and td._col_Amount_in_stock. It looked for td.id and td.Amount, which the table has never rendered, so it sorted two empty lists and passed whatever the table did. The new helper refuses a column of fewer than two cells.

Testing

• npm test checks 46 files, typechecks the three projects and passes the 15 unit tests, all reporting nothing.
• The browser suite passes 43 tests.
• no console errors on card page fails for the reason described in fix(biome.js) :: fix remaining lint issues #1366, on this branch and on the unmodified base alike.

ah, I thought this change may be a bit controversial since it touched the CI so I kept it last on the stack 😓 maybe that was a bad idea in hindsight

@lovasoa seems like I can rebase and merge from my phone if we follow the stack I of PRs I currently have setup. #1368 would be next.

if you would rather I pop this change off of this branch and rebase it onto mainline as an independent PR you can merge, I will have to wait until I get back home after work to do that

[lovasoa]

we are in no hurry, it's going to take some time on my side to process everything too!

@lovasoa intentionally left a bug in this CI to show that it would fail. will fix properly once this gets closer to being fully ready for review
