fix: correct session reset mode options in Settings UI

[GaoZzr]

Bug Description

The Session Settings dropdown in the WebUI has two bugs that prevent proper session reset mode configuration:

Bug 1: hourly instead of daily

The dropdown uses value: 'hourly' but the gateway's SessionResetPolicy (in gateway/config.py) only recognizes "daily", "idle", "both", and "none". Selecting "Scheduled Only" writes mode: hourly to config.yaml, which the gateway silently ignores — effectively behaving as mode: none.

Bug 2: Missing none option

The CLI setup wizard (hermes_cli/setup.py) offers 4 choices including "Never auto-reset (context lives until /reset or context compression)" → mode: none. This is also documented in cli-config.yaml.example and explicitly handled in gateway/session.py:

if policy.mode == "none":
    return None  # No reset

However, the WebUI dropdown only has 3 options, making it impossible to select none through the UI.

Changes

SessionSettings.vue

• Changed value: 'hourly' → value: 'daily' to match gateway expectations
• Added { label: t('settings.session.modeNone'), value: 'none' } option
• Added modeDaily i18n key (renamed from modeHourly)

i18n locale files (all 8 languages)

• Renamed modeHourly → modeDaily (same translations)
• Added modeNone translation for each language:
  • en: "Never (Manual Only)"
  • zh: "永不（仅手动）"
  • de: "Nie (nur manuell)"
  • es: "Nunca (solo manual)"
  • fr: "Jamais (manuel uniquement)"
  • ja: "なし（手動のみ）"
  • ko: "안함 (수동만)"
  • pt: "Nunca (apenas manual)"

Impact

• Users who previously selected "Scheduled Only" in WebUI were unknowingly running with an unrecognized mode (effectively none). After this fix, they'll get the intended daily behavior.
• Users who want to disable auto-reset can now do so through the UI instead of manually editing config.yaml.
