Gabriel Radureau d863d70f7a feat(bdd): magic-link BDD scenarios + bcrypt overflow fix (ADR-0028 Phase A.5)
Adds 4 BDD scenarios covering the passwordless magic-link flow:
- Happy path (request -> email arrives -> consume -> JWT)
- Token cannot be consumed twice (single-use guarantee)
- Missing token returns 400
- Unknown token returns 401

Implementation:
- features/auth/magic_link.feature with the gherkin spec
- pkg/bdd/steps/magic_link_steps.go: per-scenario unique recipient
  (`<scenario-key>-<8hex>@bdd.local`, ADR-0030), Mailpit-driven token
  extraction, regex parse of the consume URL
- pkg/bdd/steps/scenario_state.go: 2 fields added (MagicLinkEmail,
  MagicLinkToken)
- pkg/bdd/steps/steps.go: register 5 new step regexes

Bug fix exposed by the BDD run:
- pkg/user/api/magic_link_handler.go: passwordless-signup random password
  was 96 hex chars (48 bytes) which overflowed bcrypt's 72-byte input
  limit, breaking first-link signup. Reduced to 64 hex chars (32 bytes,
  256 bits entropy).

Test infra fix:
- pkg/bdd/testserver/server.go: createTestConfig() builds the
  Config literal directly (no Viper defaults), so add explicit Email +
  MagicLink config so the From address is set when the handler sends
  via local Mailpit.

Mistral wrote the feature file, magic_link_steps.go, scenario_state.go
edit, and steps.go edit autonomously in a worktree workspace. Claude
fixed the bcrypt overflow + the test-config gap exposed during verification.

Most authoring by Mistral Vibe (mistral-vibe-cli-latest).
