fix(session): require config-backed mutation authority and workspace-bound targets (#714)

Close the #714 remediation gap left at 943d402 where env-only mutation
profiles, REMOTES Timesheet defaults treated as explicit caller input, and
machine-dependent Git remotes produced false greens.

- Fail closed when mutations lack a config-backed profile with non-empty
  allowed_repositories; env ops cannot invent mutation authority.
- Preserve omitted-vs-explicit org/repo provenance through the mutation
  gate; omitted targets bind to the verified workspace repository.
- Prefer workspace-aligned Git remotes over historical Timesheet defaults
  in MCP _resolve and CLI resolve_remote.
- Centralize deterministic config-backed mutation fixtures; migrate
  mutation tests off env-only authority without weakening security
  assertions.

Full suite: 2744 passed, 6 skipped.

+## Repository scope (#714)
+
+`allowed_repositories` declares the canonical `owner/repository` slugs a profile
+may operate on:
+
+```json
+"prgs-author": {
+  "allowed_repositories": ["Scaled-Tech-Consulting/Gitea-Tools"]
+}
+```
+
+It is an **authorization boundary, not the session binding**. The binding is
+derived and enforced like this:
+
+1. The session repository is derived from the **verified, workspace-aligned git
+   remote** — never from a caller-supplied `org`/`repo` argument, and never from
+   the `REMOTES` table (whose entries are default *targets*: `prgs` defaults to
+   `Timesheet`, which is not this project).
+2. That workspace-derived slug is validated against `allowed_repositories`.
+3. The session binds immutably to that one canonical `owner/repository`. The
+   organization is derived from the slug; there is no independent,
+   caller-controlled organization value.
+4. If a profile authorizes several repositories, the verified workspace still
+   selects exactly one. A session never binds to the whole list and never
+   switches between entries.
+
+Fail-closed rules:
+
+- Activation is rejected when the workspace repository is absent from the
+  allowlist.
+- A mutation is rejected when no verified workspace repository can be
+  established.
+- A tool-level `org`/`repo` override that disagrees with the binding is rejected
+  before the mutation runs.
+- A mutation request can never establish, complete, or replace the binding.
+
+The field is **config-only**: no environment variable can widen or forge it. It
+is optional — a profile that omits it keeps the previous behaviour, so existing
+static-profile namespaces stay functional until an operator provisions the
+scope. Provisioning it is what activates enforcement for that profile.

+These tests drive the real entry points (``gitea_whoami``,

+construct a ``_SessionContext`` directly: the defect they cover is that the

+``assess_session_context`` skipped its repository/org drift checks and a
+same-host mutation against another repository was not blocked.

+The trusted repository identity comes from the workspace-aligned git remote
+(``Scaled-Tech-Consulting/Gitea-Tools`` for this checkout), never from
