Katia Bulatova e768d0a724 feat(webapp): run the dashboard agent through AWS Bedrock behind an env switch (#4609)
## What & why

The dashboard agent can now run its model calls through AWS Bedrock
instead of the direct Anthropic API, chosen by a single env switch. It's
**off by default** (`DASHBOARD_AGENT_MODEL_PROVIDER` unset ⇒
`anthropic`), so merging changes nothing at runtime — the Bedrock path
is a dormant branch until an operator sets the switch and AWS config.
The default Anthropic path is byte-for-byte unchanged.

This also carries a related tenant-isolation hardening for the agent's
delegated token (kept together deliberately — both land the agent on
Bedrock for HIPAA readiness). Refs: TRI-13251, TRI-11032.

## What's inside

**Provider seam** —
`internal-packages/dashboard-agent/src/model-provider.ts`: the registry
now holds both `anthropic` and `bedrock`; `resolveDashboardAgentModel()`
maps the canonical `"anthropic:<id>"` strings the managed prompts carry
to the active provider, and the cache-breakpoint helpers emit the active
provider's shape — Anthropic `cacheControl` vs Bedrock `cachePoint`.
Managed prompt strings stay canonical, so stored prompts don't change
meaning. Unmapped model ids throw rather than shipping a guaranteed-404
profile. All agent, watch, compaction and title callsites route through
the resolver; the `dashboardAgentModelKey` locals override (test mock
injection) is preserved.

**Cache telemetry** — `step-cache.ts`: cache token usage is read from
the active provider (Anthropic reports it on provider metadata; Bedrock
reports the write on metadata and the read via standard usage), so
`gen_ai.usage.cache_*` is populated on both. This also fixes a latent
ordering bug where step attributes could null-overwrite the prompt-cache
read count.

**Webapp callsites** — `dashboardAgentHeadStart.server.ts` and the
head-start route resolve the model and the cache breakpoint through the
same seam, so the warm-up prefix and the following turn share one
provider. The head-start firing gate is provider-aware: on Bedrock it
gates on `AWS_REGION` and lets the SDK resolve credentials (IAM role /
static keys / session token / bearer), so a role-based deploy still
warms; on Anthropic it stays `Boolean(ANTHROPIC_API_KEY)`.
`app/env.server.ts` gains the optional AWS vars and validates
`DASHBOARD_AGENT_MODEL_PROVIDER`. `ANTHROPIC_API_KEY` is untouched and
not required on a Bedrock deploy.

**Tenant-isolation hardening** —
`internal-packages/rbac/src/fallback.ts`: for a **scoped** context, the
OSS `authenticateUserActor` now applies the same membership floor as the
session path — a delegated user-actor token whose user is not a member
of the scoped org/project is denied (403). Unscoped tokens keep their
prior behavior (no tenant claim, no lookup). The user lookup falls back
replica→primary so replication lag can't spuriously 401 a just-joined
member. Members and admins are unaffected. Previously this invariant
held only through per-route discipline; this makes it structural.

## Enabling Bedrock (later, ops)

- Set `DASHBOARD_AGENT_MODEL_PROVIDER=bedrock` **identically** in both
the webapp and the agent task container — the webapp warms the cache
prefix and the task reads it, so a split would silently miss the cache.
- Set `AWS_REGION` and provide credentials the Bedrock SDK can resolve
(IAM role preferred). For v1 this runs **without** an Anthropic API key.
Note: with no Anthropic key set, rollback is "turn the agent off", not
"unset the switch" (unsetting falls back to the Anthropic provider,
which then has no key).
- Two things to confirm before rollout: the Sonnet inference-profile id
is validated against the SDK's own model-id union but still warrants a
live smoke test; and Bedrock prompt caching for Sonnet is a 5-minute
window (not Anthropic's 1h), so input-token cost rises when flipped.

## Testing

Unit tests cover both provider paths: the provider switch and
per-provider cache shapes, a structural regex asserting Bedrock ids are
real inference profiles (not an echo of the table), the split-metadata
cache telemetry, and real-Postgres RBAC tests — member allowed, scoped
non-member denied (org-only and project-only), missing user → 401, admin
non-member exempt, unscoped success. `typecheck --filter webapp` and the
dashboard-agent + rbac suites pass.
