frontend: add console best practices

[malinskibeniamin]

Applies fixes from react-best-practices skill

New Utilities

1. src/utils/regex.ts - Cached search regex with proper escaping

• escapeRegex() - escapes special regex characters
• getSearchRegex() - returns cached, case-insensitive RegExp for search queries
• LRU-style cache (max 100 entries) to avoid repeated regex compilation

2. src/utils/array-transforms.ts - Efficient array helpers

• filterMap() - single-pass filter and map operation
• partition() - split array into multiple buckets by classifier
• partitionBy() - two-way partition based on predicate

3. src/hooks/use-safe-local-storage.ts - Safe localStorage access

• useSafeLocalStorage() hook - handles incognito mode, quota errors, SSR
• getLocalStorageFlag() / setLocalStorageFlag() - simple boolean flag helpers

Refactors

Search filtering standardization

Replaced duplicated try/catch regex patterns across 12 files with getSearchRegex():

• acl-list.tsx (4 places)
• role-details.tsx
• admin-users.tsx
• cluster-details.tsx
• connect/overview.tsx
• group-list.tsx
• pipelines-list.tsx
• secrets-list.tsx
• schema-list.tsx
• topic-list.tsx
• transforms-list.tsx

Performance improvements

• rp-connect/utils/yaml.ts - use Set instead of Array.includes() for label lookups
• topic-filters-session.ts - module-level cache to avoid repeated sessionStorage parsing
• topic-produce.tsx - watch individual form fields instead of objects to minimize effect reruns

Simplifications

• ai-agent-configuration-tab.tsx - removed unnecessary useMemo wrappers for simple boolean/array derivations

Safe storage

• banner.tsx - uses new safe localStorage helpers instead of direct localStorage access

Not merging for now - postponing for a future Console release. Going to keep it open
