docs: optimize navigation titles for improved sidebar UX (#572)

## Summary

Optimized 17 documentation page titles to improve sidebar navigation
readability and user experience. Shortened overly long titles (70-91
characters) to concise, scannable formats (20-35 characters) while
preserving all SEO metadata and content quality.

## Problem Statement

The documentation sidebar was displaying excessively long page titles
that created several UX issues:

- **Poor Readability**: Titles were truncated or wrapped awkwardly in
sidebar navigation
- **Cognitive Load**: Users had difficulty quickly scanning navigation
options
- **Inconsistent Design**: Mixed long and short titles created visual
inconsistency
- **Mobile Experience**: Extra long titles were particularly problematic
on smaller screens

### Examples of Problematic Titles:
- "How is blockchain transforming banking and financial services?
Complete BFSI use case guide" (91 chars)
- "What are smart contracts? Complete business guide to automated
blockchain agreements" (84 chars)
- "Asset Tokenization UI Customization: Complete Guide to Frontend
Branding & Development" (87 chars)

## Solution

Systematically shortened titles across four main documentation sections
while maintaining semantic meaning:

### 1. Knowledge Bank (10 files optimized)
- **Before**: "How is blockchain transforming banking and financial
services? Complete BFSI use case guide"
- **After**: "Banking & Financial Services Use Cases"

### 2. Application Kits (2 files optimized)
- **Before**: "Asset Tokenization UI Customization: Complete Guide to
Frontend Branding & Development"
- **After**: "UI Customization & Branding"

### 3. Platform Deployment (3 files optimized)
- **Before**: "How do I choose the right deployment plan for enterprise
blockchain workloads?"
- **After**: "Choosing Deployment Plans"

### 4. Building Guides (2 files optimized)
- **Before**: "How to add private keys to your EVM blockchain node for
transaction signing"
- **After**: "Adding Private Keys"

## Technical Implementation

### Changes Made
- ✅ Updated `title` field in frontmatter of 17 MDX files
- ✅ Preserved all `description` fields (SEO metadata intact)
- ✅ Maintained all `keywords` arrays where present
- ✅ No content or functional changes to page bodies
- ✅ No changes to URL structure or routing
