8307eadda2 [http_request] Lowercase collect headers at config time, eliminate per-request overhead 
Move header lowercasing from the per-request start() path to config time:
- Python codegen now lowercases collect_headers values before passing to C++
- add_collect_header() stores values as-is (already lowered by Python)
- start() with std::vector is now a direct passthrough to perform()
- Deprecated std::set overload still lowercases for external callers

Rename collect_headers_ to lower_case_collect_headers_ and update all
parameter names throughout the chain to make the lowercase invariant
explicit in the API contract.

This eliminates per-request allocation of a temporary vector and
str_lower_case() calls on every HTTP request, reducing stack usage
in the perform() call chain where stack space is critical for HTTPS
TLS handshakes.

8120bd373c [http_request] Replace std::map/std::set/std::list with std::vector for response headers 
Replace heavy STL containers with simple std::vector and linear scan
for response header collection. This eliminates red-black tree (_Rb_tree)
and hash table template instantiations that are unnecessary for the small
number of headers typically collected (1-5 elements).

Changes:
- response_headers_: std::map<string, list<string>> -> std::vector<Header>
- collect_headers_: std::set<string> -> std::vector<string>
- perform() signature: std::set -> std::vector
- Add should_collect_header() inline helper for linear scan
- Lowercase collect_headers at config/insertion time instead of per-request
- IDF UserData now holds references to container's vector instead of
  owning a separate map that gets moved after the request
- Reuse existing Header struct instead of std::pair

Reduces stack usage in perform() and eliminates STL container overhead
on memory-constrained ESP devices.
