* Switch Cypress to use shared ESLint config
* Run --fix in Cypress
* Manually fix remaining lint issues in Cypress
* Switch Playwright to use shared ESLint config
* Run --fix in Playwright
* Manually fix remaining lint issues in Playwright
* Install and cache web app deps during Cypress CI builds
This also caches the types and client package. That isn't needed currently
since it uses prepackaged versions of those, but I imagine we might change
that at some point.
* Run e2e-tests-check when ESLint plugin is updated
* Change E2E test GHA caching to cache all of web app node_modules
* Fix mismatch between cache save and restore
* Try bumping cache keys
* Copy step to install dependencies to server.run_cypress.sh
I don't know how this must've worked before, but if this fixes the issue,
it seems like neither Cypress nor Playwright actually use the cached
depenendencies.
* Try disabling caching entirely for Cypress tests
* Try bypassing makefile?
* Try also manually building dependencies in run_specs.sh
I don't know why this appears to duplicate run_cypress.sh and
run_playwright.sh, both of which are called run_test.sh which
might not be used any more as best I can tell.
* Try installing the web app dependencies in yet another place
* Disable the extra steps in server.prepare.sh specifically for Cypress
* Revert changes to update cache key and disable web app depenedency cache on Cypress builds
