Each GHL location can now have its own Cast API key and sender ID stored
in MongoDB. Falls back to global CAST_API_KEY / CAST_SENDER_ID env vars
when not set per-location.
Admin endpoints (all require Authorization: Bearer <INBOUND_API_KEY>):
GET /api/admin/locations — list all locations
GET /api/admin/locations/{locationId}/config — get location config
PUT /api/admin/locations/{locationId}/config — set sender_id + cast_api_key
Cast API key is masked in GET responses (first 12 chars + "...").
Replaces the /sender-id endpoint deployed in the previous commit.
Also adds FUTURE_DEV.md documenting the migration path to Infisical
for secret management, plus MongoDB security hardening checklist.

Allows each GHL sub-account to use a different Cast sender ID instead of
the global CAST_SENDER_ID default.
- store.TokenRecord gains a sender_id field (MongoDB)
- store.UpdateSenderID method to set it per location
- cast.Client.SendSMS accepts a senderID override param (empty = use
client-level default)
- webhook.processOutbound reads the location's sender_id from the token
record and passes it to Cast
- new admin handler: PUT /api/admin/locations/{locationId}/sender-id
protected by Authorization: Bearer <INBOUND_API_KEY>

- internal/ghl/oauth.go:186: defer func(){ _ = resp.Body.Close() }()
- internal/cast/client_test.go: prefix all json.Decode/Encode calls with _ =
- internal/ghl/oauth_test.go: _ = r.ParseForm(), _, _ = w.Write(...)
golangci-lint exclusion rules in v2 are not suppressing test file errcheck
as expected, so fixes are applied directly in source.

Production fixes:
- cmd/server/main.go: refactor to run() helper to eliminate exitAfterDefer
(os.Exit in main() no longer bypasses deferred s.Close)
- internal/cast/client.go: use _ = resp.Body.Close() (errcheck)
- internal/ghl/api.go: wrap both defers as func(){ _ = resp.Body.Close() }()
Test fixes:
- internal/cast/client_test.go: replace err.(*CastAPIError) type assertions
with errors.As (errorlint)
Config:
- .golangci.yml: use explicit path regex .*_test\\.go and add errorlint
to test-file exclusions
