Support multi-line shipping addresses and fix critical npm vulnerabilities

[Copilot]

Shipping addresses require multi-line input. Users naturally press Enter for new lines rather than SHIFT+ENTER, but the single-line text input prevented this.

Changes

UI Enhancement

• Changed shipping address field from <input type="text"> to <textarea rows="3"> in views/product_detail.ejs
• Preserves Bootstrap styling and form behavior

- <input type="text" class="form-control" name="address" id="address" placeholder="Shipping address..." required>
+ <textarea class="form-control" name="address" id="address" placeholder="Shipping address..." required rows="3"></textarea>

Backend already handles newline characters correctly via params.address passthrough to database.

Security Fixes

Updated vulnerable dependencies to patched versions:

Package	Version	Vulnerability
body-parser	1.13.3 → 1.20.3	DoS via URL encoding
debug	2.2.0 → 2.6.9	ReDoS
ejs	2.7.4 → 3.1.10	Template injection (critical)
morgan	1.6.1 → 1.10.1	Code injection
express	4.13.1 → 4.21.2	Transitive vulnerabilities

Added npm override to force abandoned ejs-locals (2012) to use secure ejs 3.1.10 instead of vulnerable 0.8.8.

Application tested and functional with all dependency updates.
