The test_examples_protocol_https_request_rom_impl test on ESP32-C2 with
the ROM mbedTLS implementation hits a public TLS endpoint
(tls13.browserleaks.com / www.howsmyssl.com) for five sequential
sub-tests. CI runs frequently fail mid-test with one of:
* mbedtls_ssl_handshake returned -0x7780
(MBEDTLS_ERR_SSL_FATAL_ALERT_MESSAGE - server-side fatal alert)
* esp-tls: [sock=NN] select() timeout
* esp-tls: Failed to open new connection in specified timeout
In a representative log the first three sub-tests succeed and only the
fourth/fifth fail, which is consistent with rate-limiting or transient
server unavailability rather than a device bug. Mark the test as
flaky with up to two reruns (10 s delay) so a single transient remote
failure does not fail the CI job.
Also align this test with the rest of the file by injecting the host
timestamp via NVS (write_time_to_nvs) so the device clock no longer
depends on a previous boot's persisted SNTP result, removing one more
source of CI flakiness on first-boot or after NVS erase.

Replace erase_nvs + SNTP time sync with direct NVS timestamp injection
from the pytest host. This eliminates CI flakiness caused by NTP servers
being unreachable from the CI lab network.
Changes:
- Add write_time_to_nvs() helper that generates an NVS partition image
with the current host timestamp and flashes it to the DUT before each
test. The firmware reads this via the existing update_time_from_nvs()
path and skips SNTP entirely.
- Remove @pytest.mark.parametrize('erase_nvs', ['y']) from all 4
Ethernet-based tests since NVS is now written with valid data.
This commit refactors the script responsible for starting a Python-based HTTPS server
to align with the latest Python version's requirements and best practices.
