PocketBase: v0.26.0 Release

> _To update the prebuilt executable you can run `./pocketbase update`._ - ⚠️ Replaced `aws-sdk-go-v2` and `gocloud.dev/blob` with custom lighter implementation ([#6562](https://github.com/pocketbase/pocketbase/discussions/6562)). As a side-effect of the dependency removal, the binary size has been reduced with ~10MB and builds ~30% faster. _Although the change is expected to be backward-compatible, I'd recommend to test first locally the new version with your S3 provider (if you use S3 for files storage and backups)._ - ⚠️ Prioritized the user submitted non-empty `createData.email` (_it will be unverified_) when creating the PocketBase user during the first OAuth2 auth. - Load the request info context during password/OAuth2/OTP authentication ([#6402](https://github.com/pocketbase/pocketbase/issues/6402)). This could be useful in case you want to target the auth method as part of the MFA and Auth API rules. For example, to disable MFA for the OAuth2 auth could be expressed as `@request.context != "oauth2"` MFA rule. - Added `store.Store.SetFunc(key, func(old T) new T)` to set/update a store value with the return result of the callback in a concurrent safe manner. - Added `subscription.Message.WriteSSE(w, id)` for writing an SSE formatted message into the provided writer interface (_used mostly to assist with the unit testing_). - Added `$os.stat(file)` JSVM helper ([#6407](https://github.com/pocketbase/pocketbase/discussions/6407)). - Added log warning for `async` marked JSVM handlers and resolve when possible the returned `Promise` as fallback ([#6476](https://github.com/pocketbase/pocketbase/issues/6476)). - Allowed calling `cronAdd`, `cronRemove` from inside other JSVM handlers ([#6481](https://github.com/pocketbase/pocketbase/discussions/6481)). - Bumped the default request read and write timeouts to 5mins (_old 3mins_) to accommodate slower internet connections and larger file uploads/downloads. _If you want to change them you can modify the `OnServe` hook's `ServeEvent.ReadTimeout/WriteTimeout` fields as shown in [#6550](https://github.com/pocketbase/pocketbase/discussions/6550#discussioncomment-12364515)._ - Normalized the `@request.auth.*` and `@request.body.*` back relations resolver to always return `null` when the relation field is pointing to a different collection ([#6590](https://github.com/pocketbase/pocketbase/discussions/6590#discussioncomment-12496581)). - Other minor improvements (_fixed query dev log nested parameters output, reintroduced `DynamicModel` object/array props reflect types caching, updated Go and npm deps, etc._)
