Migrate Edit/Create routes to react-query where we have regressions

To ensure queries get invalidated as expected when editing in Agreements and Licenses.

ViewRoutes were migrated earlier, but no longer ghet invalidated properly when edits are made or new objects created. This work covers fixing that

Covers:

AGREEMENTS

• AgreementEditRoute ✓
• AgreementLineEditRoute ✓
• AgreementCreateRoute ✓
• AgreementLineCreateRoute ✓
• EresourceEditRoute ✓
• PlatformEditRoute ✓

LICENSES

• CreateAmendmentRoute ✓
• EditAmendmentRoute ✓
• EditLicenseRoute ✓

NOTE: We did not migrate Notes or UrlCustomisers at all previously, so there are no regressions needed there for this issue, although all their routes should be migrated together in future.

Also does not cover stuff left app wide, such as the basket route functionality

Does not cover:

AGREEMENTS

• UrlCustomizerEditRoute
• NoteCreateRoute
• NoteEditRoute

LICENSES

• NoteCreateRoute
• NoteEditRoute
