fix(headers): match header patterns whatever the name casing (#136)

* fix(headers): match header patterns whatever the name casing

wappalyzer-core lowercases its header pattern keys, but getHeaders kept
the caller's casing, so { 'X-Powered-By': 'Express' } or
{ Server: 'nginx/1.25.3' } detected nothing. Header names are now
lowercased, names that differ only by case are merged, and an array
value is no longer wrapped in another array.

* fix(headers): keep detections when the header map is missing

Object.entries and Object.keys throw on null or undefined, so a caller
with only HTML, or a missing Set-Cookie map, aborted analysis. A missing
map is now no headers. Tests lock case-merged values and every value of
a multi-value header, which an overwrite left green.

* refactor(cookies): read every Set-Cookie from the normalized map

Drop lodash. castArray was the last call.
