Breaking API change — no deprecation period

Removing IMPS from the paymentRails enum is a non-backwards-compatible change. InrAccountInfo is composed into both PaymentInrAccountInfo (response) and InrExternalAccountInfo (used in external-account creation request bodies at the /external-accounts endpoint). Any existing API clients that currently supply "IMPS" in the paymentRails array when creating or reading an INR external account will:

  1. Fail schema validation on requests that include IMPS.
  2. Receive unexpected responses if the backend still returns IMPS (which isn't changed by this PR).

Before hard-removing the value, the standard approach would be to:

  1. Deprecate IMPS in the schema (add a description/deprecated: true annotation) and give integrators a migration window.
  2. Only remove the value once all in-flight usage is confirmed to be zero.

If IMPS has already been sunset at the backend level and zero customers are using it, that context would be helpful to document here (e.g., a comment or PR note).

**Breaking API change — no deprecation period**

Removing `IMPS` from the `paymentRails` enum is a non-backwards-compatible change. `InrAccountInfo` is composed into both `PaymentInrAccountInfo` (response) **and** `InrExternalAccountInfo` (used in external-account creation request bodies at the `/external-accounts` endpoint). Any existing API clients that currently supply `"IMPS"` in the `paymentRails` array when creating or reading an INR external account will:

1. Fail schema validation on requests that include `IMPS`.
2. Receive unexpected responses if the backend still returns `IMPS` (which isn't changed by this PR).

Before hard-removing the value, the standard approach would be to:
1. Deprecate `IMPS` in the schema (add a description/`deprecated: true` annotation) and give integrators a migration window.
2. Only remove the value once all in-flight usage is confirmed to be zero.

If IMPS has already been sunset at the backend level and zero customers are using it, that context would be helpful to document here (e.g., a comment or PR note).

How can I resolve this? If you propose a fix, please make it concise.
