As as user I want links which qualify for bridge to truly opened in bridge.
**Problem:**
If a user clicks the edit pen too quickly after loading the page then the Bridge hasn't finished loading and the user gets thrown to Wikidata instead.
A smaller `init` file will reduce the time it takes for the module to be loaded & consequently link listeners to be attached.
**BDD**
GIVEN an article
AND a Bridge-enabled infobox
WHEN loading the page
AND clicking the edit pen shortly afterwards
THEN the Bridge opens
**Acceptance criteria:**
[ ] time between page loading and Bridge being ready is significantly reduced
**Tech notes**
* creation of `ServiceRepositories` is moved out of init - either into a dedicated module, or into app
* pass along what is required to create its contents (e.g. `ForeignApi`)
* `ServiceRepositories` is created using instances of data-access "repositories". These can be huge and are not technically needed at init-time
* this was researched in {T233305}
