PR description:

This PR, based on the work by @icosivi as discussed and agreed with @bsunanda and N. Koss, removes from the ETL TDR description as implemented in scenario D53 the front thermal screen, which is already included in the volume outside EndcapTimingLayer.

I have taken the opportunity to move the main volume from a polycone to a tubs (i.e. a cyclindrical shell), which is simpler for the geometry navigation.

This PR fully embeds #29647, it may be rebased after the integration of that.

PR validation:

@icosivi has verified the positions and checked that no overlap is present after this update. I have checked that the volume paths and DetIds are identical after the update (as they should), just longitudinal positions are shifted along z (as expected). The initial part of the dump differences is:

The latest fix is needed to avoid an overlap with the mother volume, not present in the version with the polycone by @icosivi . The g4OverlapsCheck shows no issue.
