refactor: additional Nuxt review findings

[dinooo13]

Summary

Addresses the additional observations from the initial code review (#14). These are deeper structural improvements to align with Nuxt best practices.

Changes

• Remove unused @vueuse/nuxt — Module was registered but no VueUse composables are used in the codebase. useColorMode is already provided by Nuxt UI.
• Update compatibilityDate — Bumped from 2024-11-01 to 2025-03-01 to match Nuxt 4.
• Re-enable @typescript-eslint/no-explicit-any — Was globally disabled but no any usages exist in the codebase. Removed the override to keep the stricter default.
• Extract usePageSeo composable — Replaces 5 duplicated useSeoMeta({ title, ogTitle, description, ogDescription }) blocks across all pages with a single composable in app/composables/usePageSeo.ts.
• Extract shared ContentButton type — LabsTeaser and SpeakingTeaser both had identical 7-line inline button types. Moved to app/utils/types.ts and referenced via Nuxt auto-import.
• Optimize [slug] page queries — Both labs/[slug].vue and speaking/[slug].vue were fetching ALL entries, sorting, then filtering by slug. Now they query directly by stem which is more efficient.
• Add defineOgImage() — The nuxt-og-image module was installed but never activated. Added defineOgImage() to all 5 pages so OG images are generated from page meta.
• Document deploy workflow — Added a comment explaining why dangerous-clean-slate: true is used in the FTP deploy step.

Test plan

• pnpm run lint passes
• pnpm run typecheck passes
• Verify all pages still render correctly
• Verify OG images are generated at /__og-image__/ routes
• Verify content queries by stem resolve correctly for all lab and talk detail pages

@claude fix the lint

[dinooo13]

Fixed! The lint failure was @typescript-eslint/prefer-nullish-coalescing — the || operators in usePageSeo.ts and speaking/[slug].vue were flagged because the operands are optional strings. Replaced with ?? in both places.
