STRATCONN-6441 - [Facebook CAPI] - removing flags from actions

[joe-ayoub-segment]

Removing flags after Facebook CAPI refactor.

Removes feature flags from the Facebook Conversions API destination actions. Previously, each action had two code paths — a legacy inline implementation and a newer shared send() function gated behind a feature flag. Since all flags have been fully rolled out, this PR removes the flag checks and legacy code paths, making the shared send() function the single implementation for all actions. Also cleans up redundant files (constants.ts, utils.ts, fb-capi-* modules) whose functionality has been consolidated into shared/constants.ts and shared/functions.ts.

export const FEATURE_FLAG_ADD_TO_CART = 'FB_CAPI_REFACTOR_ADD_TO_CART_EVENT'

export const FEATURE_FLAG_CUSTOM = 'FB_CAPI_REFACTOR_CUSTOM_EVENT'

export const FEATURE_FLAG_INITIATE_CHECKOUT = 'FB_CAPI_REFACTOR_INITIATE_CHECKOUT_EVENT'

export const FEATURE_FLAG_PAGE_VIEW = 'FB_CAPI_REFACTOR_PAGE_VIEW_EVENT'

export const FEATURE_FLAG_PURCHASE = 'FB_CAPI_REFACTOR_PURCHASE_EVENT'

export const FEATURE_FLAG_SEARCH = 'FB_CAPI_REFACTOR_SEARCH_EVENT'

export const FEATURE_FLAG_VIEW_CONTENT = 'FB_CAPI_REFACTOR_VIEW_CONTENT_EVENT'

Testing

Deployed to staging for sanity check.

Pull request overview

This PR removes per-action feature-flag branching and legacy, duplicated request/validation logic in the Facebook Conversions API destination actions, consolidating behavior around the shared send() helper.

Changes:

• Removed FEATURE_FLAG_* gating branches from multiple Facebook CAPI actions and routed execution through the shared send() path.
• Deleted legacy helper modules (fb-capi-user-data.ts, fb-capi-properties.ts, fb-capi-app-data.ts) that previously contained validation/hashing/app-data logic.
• Simplified action implementations by trimming imports and deferring validation/request construction to shared helpers.
