fix: misc frontend fixes for agent log, login, search settings (#16137)

### What problem does this PR solve?

fix: misc frontend fixes for agent log, login, search settings
- agent-log: restore server-side pagination on export and search;
replace hardcoded labels with i18n keys; switch container to
text-text-primary
- login: validate register nickname against NICKNAME_PATTERN with
reusable setting i18n
- next-search: align llm_setting schema with chat (LlmSettingFieldSchema
+ LLMIdFormField nested, LlmSettingEnabledSchema at form
root) so the slider Switch reads the correct path; strip *Enabled flags
before submit to avoid backend "Unrecognized field name"
  errors
  - locales: add common.reset (zh/en)
  - skills/go-naming: fix relative link to rules/named.md
