* 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 * Fediverse chat auth via OTP * Increase validity time just in case * Add fediverse auth into auth modal * Text, validation, cleanup updates for fedi auth * Fix typo * Remove unused images * Remove unused file * Add chat display name to auth modal text
