Bump aidbox-ts-sdk: fix extension on nested elements

[aleksandrkislitsyn]

Bumps the aidbox-ts-sdk submodule 484b967 → bf86fae (current sdk master) to pick up aidbox-ts-sdk#150.

What it fixes

The FHIR editor falsely flagged a valid extension on nested elements as an Unknown property, and omitted it from autocomplete — e.g. QuestionnaireResponse.item[].extension, Patient.contact[].extension. #150 fixes resolveElements to include the universal element properties (id/extension, plus modifierExtension on BackboneElements/resources) that a StructureDefinition differential doesn't repeat for nested elements.

Fixes HealthSamurai/sansara#8121.

Note on the pointer change

The previous pin 484b967 ("indent with two spaces") was an sdk commit that was never merged to sdk master — it targeted the old indentUnit/insertTab Tab-handling code, which sdk master has since replaced with computeYamlNewlineIndent. So this bump moves forward to sdk master's current indentation handling; the orphaned commit is superseded, not a live feature being dropped. (Worth a quick confirm that 2-space editor indentation still behaves as expected on master — independent of this fix.)

⚠️ Hold / needs re-pointing.

This bump targets sdk master (bf86fae), but investigation showed aidbox-ui actually tracks the sdk development branch (current pin 484b967 is development's tip, ~296 commits ahead of master). Bumping to master regresses APIs aidbox-ui depends on (reverseIcon/contentStyle on TableHead, CodeEditor props) — hence the typecheck failure here.

The #8121 fix has been re-applied onto development in aidbox-ts-sdk#151. Once that merges, I'll re-point this PR to development's new tip (fix + all current APIs), which will make typecheck pass.

Re-pointed: now bumps aidbox-ts-sdk 484b967 → 6a29dc0 (development tip, which merged aidbox-ts-sdk#151). This is a clean forward bump from master's current pin — it adds the #8121 fix while keeping all the APIs aidbox-ui depends on, so the earlier typecheck regression is resolved.
