Félix Malfait 667cb95730 fix(sso): accept HTTP-POST binding and surface descriptive parser errors (#21051)
Fixes https://github.com/twentyhq/twenty/issues/21044

## Summary
- Closes [#490](https://github.com/twentyhq/private-issues/issues/490) —
JumpCloud customers (and anyone else whose IdP only advertises
`HTTP-POST` for `SingleSignOnService`) could not upload their SAML
metadata; the parser silently rejected them with a generic `Invalid
file` toast.
- The SAML IdP metadata parser now falls back to `HTTP-POST` when
`HTTP-Redirect` is not advertised. Both are valid SAML 2.0 bindings.
- The parser now returns a descriptive `reason` string (Zod issues +
custom errors) instead of an opaque `error: unknown`, and the upload
snack bar surfaces it so the customer can self-diagnose (e.g. `entityID:
entityID is not a valid URL` if they forgot to fill in their IdP Entity
ID).
- Added unit tests for HTTP-POST-only metadata, HTTP-Redirect
preference, and each descriptive-error path.

## Test plan
- [x] `npx jest parseSAMLMetadataFromXMLFile
--config=packages/twenty-front/jest.config.mjs` — 8/8 pass
- [x] `npx oxlint -c packages/twenty-front/.oxlintrc.json` on changed
files — clean
- [x] `npx oxfmt --check` on changed files — clean
- [ ] Manual: upload the customer's JumpCloud metadata (HTTP-POST only,
placeholder `entityID`) and confirm the error now says `Invalid file:
entityID: entityID is not a valid URL` instead of `Invalid file`
- [ ] Manual: upload metadata with a real `entityID` and HTTP-POST-only
binding, confirm the form populates correctly

Define objects, fields, and views as code:

import { defineObject, FieldType } from 'twenty-sdk/define';

export default defineObject({
  nameSingular: 'deal',
  namePlural: 'deals',
  labelSingular: 'Deal',
  labelPlural: 'Deals',
  fields: [
    { name: 'name', label: 'Name', type: FieldType.TEXT },
    { name: 'amount', label: 'Amount', type: FieldType.CURRENCY },
    { name: 'closeDate', label: 'Close Date', type: FieldType.DATE_TIME },
  ],
});

Then ship it to your workspace:

npx twenty app:publish --private
