fix: gateway config debt — missing keys, broken fallbacks, Discord skill limit

Resolves #328. Addresses 6 issues from the empirical audit 2026-04-12.

gateway/config.py:
- Validate idle_minutes, at_hour, and mode at construction time in
  SessionResetPolicy.from_dict — reject 0, negative, non-integer,
  out-of-range, and absurdly large values before they reach runtime
- Add API_SERVER_KEY validation: error-level log when API server is
  bound to 0.0.0.0 without a key (open relay), warning on localhost
- Add provider fallback validation: when fallback_model references
  openrouter/anthropic/openai/nous but the corresponding API key is
  not set, log a warning that fallback will fail at runtime
- Expand weak credential guard to cover OPENROUTER_API_KEY,
  ANTHROPIC_API_KEY, OPENAI_API_KEY, NOUS_API_KEY
- Wire discord.skill_slash_commands config.yaml key to env var

gateway/platforms/discord.py:
- Add DISCORD_SKILL_SLASH_COMMANDS=false config option to disable
  skill slash command registration entirely — resolves the 100-command
  limit that left 279 skills unregistered. Skills remain accessible
  via /skill or text mention when disabled
- Improve warning message with remediation instructions

gateway/platforms/api_server.py:
- Add startup warning when API server has no API_SERVER_KEY:
  error-level on non-localhost bind, warning on localhost

tests/test_gateway_config_debt_328.py:
- 14 tests for SessionResetPolicy validation (zero, negative, string,
  overflow, boundary values for idle_minutes, at_hour, mode)
- Tests for API key validation and weak credential expansion
