juergen 30670de93b fix pale colours and map driverless print options
ci/woodpecker/push/build Pipeline was successful
Details 
Set *DefaultBRColorMode: None in the vendor PPD so every job sends
<</UseCIEColor false>>: Brother's Normal/Vivid modes enable the printer's
own CIE conversion, which washed the colours out.

Add six APPrinterPreset entries mapping print-color-mode and
print-quality from driverless (AirPrint/IPP) clients onto the Brother
device options; they use the notation CUPS generates itself (Apple
metadata as 'key value' pairs, PPD options as '*Name Value'), because
key=value strings are silently discarded. print-quality is 3/4/5.

Add the PRINTER_OPTIONS env var: whitespace-separated key=value pairs
applied as queue defaults on every start via lpadmin -o, validated
against the queue's PPD, with warnings instead of a failed startup.

Document all of it in the README. The VividNoCIE candidate was dropped
after test prints showed no difference from None. Archive the OpenSpec
change and sync the printserver/cups spec with the two new
requirements.

juergen 7f26ca4f2f Fail loudly when CUPS cannot bind port 631
ci/woodpecker/push/build Pipeline was successful
Details 
The queue was still advertised over mDNS while cupsd never bound TCP 631:
a rootless Podman container on the host network cannot bind the privileged
port. Apple clients then discovered a printer they could not reach and
reported a confusing _ipps connection failure.

* entrypoint.sh: verify that CUPS accepts connections on 631 after startup
  and exit with an actionable message otherwise
* entrypoint.sh: mark the script executable in the repository
* cupsd.conf: drop BrowseRemoteProtocols, which CUPS 2.4 no longer supports
  and which logs an error on every start
* README: add a troubleshooting section for the port-binding failure and the
  _ipps/TLS certificate requirement, and document the /etc/cups bind-mount
  caveat plus the CUPS 3 PPD deprecation

juergen 30c685e085 Print via Brother BR-Script3 PostScript instead of the vendor driver 
The HL-4150CDN emulates PostScript 3, so CUPS converts client documents to PostScript and forwards them to socket://<ip>:9100. The official BR-Script3 PPD turns device options (tray, duplex, colour, media type, toner save, ...) into setpagedevice instructions. This drops the i386 multiarch runtime and the broken Brother vendor filter chain, and removes the unused Brother Linux packages from the repo.
