Replace errors.New("location not found") string with a package-level
sentinel var so callers can use errors.Is() instead of string comparison,
which errorlint flags as unsafe.

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>

Complete MVP implementation of the Cast GHL Conversation Provider bridge:
- Go module setup with chi router and mongo-driver dependencies
- Config loading with env var validation and defaults
- MongoDB token store with upsert, get, update, delete operations
- Cast.ph SMS client with 429 retry logic and typed errors
- Phone number normalization (E.164 ↔ Philippine local format)
- GHL OAuth 2.0 install/callback/refresh flow
- GHL webhook handler with ECDSA signature verification (async dispatch)
- GHL API client for message status updates and inbound message stubs
- Multi-stage Dockerfile, docker-compose with MongoDB, Woodpecker CI pipeline
- Unit tests for phone normalization, Cast client, GHL webhook, and OAuth handlers
