Recurring transactions (#271)

* Implement recurring transactions support

* Amount fix

* Hide section when any filter is applied

* Add automatic identify feature

Automatic identification runs after:

  - Plaid sync completes
  - SimpleFIN sync completes
  - LunchFlow sync completes
- Any new provider that we create.

* Fix linter and tests

* Fix address review

* FIX proper text sizing

* Fix further linter

Use circular distance to handle month-boundary wrapping

* normalize to a circular representation before computing the median

* Better tests validation

* Added some UI info

Fix pattern identification, last recurrent transaction needs to happened within the last 45 days.

* Fix styling

* Revert text subdued look

* Match structure of the other sections

* Styling

* Restore positive amounts styling

* Shorten label for UI styling
