IndieAuth support (#1811)
* Able to authenticate user against IndieAuth. For #1273 * WIP server indieauth endpoint. For https://github.com/owncast/owncast/issues/1272 * Add migration to remove access tokens from user * Add authenticated bool to user for display purposes * Add indieauth modal and auth flair to display names. For #1273 * Validate URLs and display errors * Renames, cleanups * Handle relative auth endpoint paths. Add error handling for missing redirects. * Disallow using display names in use by registered users. Closes #1810 * Verify code verifier via code challenge on callback * Use relative path to authorization_endpoint * Post-rebase fixes * Use a timestamp instead of a bool for authenticated * Propertly handle and display error in modal * Use auth'ed timestamp to derive authenticated flag to display in chat * don't redirect unless a URL is present avoids redirecting to `undefined` if there was an error * improve error message if owncast server URL isn't set * fix IndieAuth PKCE implementation use SHA256 instead of SHA1, generates a longer code verifier (must be 43-128 chars long), fixes URL-safe SHA256 encoding * return real profile data for IndieAuth response * check the code verifier in the IndieAuth server * Linting * Add new chat settings modal anad split up indieauth ui * Remove logging error * Update the IndieAuth modal UI. For #1273 * Add IndieAuth repsonse error checking * Disable IndieAuth client if server URL is not set. * Add explicit error messages for specific error types * Fix bad logic * Return OAuth-keyed error responses for indieauth server * Display IndieAuth error in plain text with link to return to main page * Remove redundant check * Add additional detail to error * Hide IndieAuth details behind disclosure details * Break out migration into two steps because some people have been runing dev in production * Add auth option to user dropdown Co-authored-by: Aaron Parecki <aaron@parecki.com>
