feat(cli): Support configuration profiles for common option sets

[berntpopp]

The CLI commands, particularly phentrieve query and phentrieve text process, have a significant number of options. To improve usability for common workflows, allow users to define named "profiles" in the phentrieve.yaml configuration file. These profiles would pre-set groups of command-line options.

Example phentrieve.yaml:

profiles:
  high_recall_german:
    command: text process
    language: de
    strategy: semantic
    model_name: "jinaai/jina-embeddings-v2-base-de"
    similarity_threshold: 0.2
    enable_reranker: true
    reranker_mode: monolingual
  precise_english_query:
    command: query
    model_name: "FremyCompany/BioLORD-2023-M"
    similarity_threshold: 0.5
    num_results: 5
    enable_reranker: true
    rerank_count: 20

CLI Invocation:
phentrieve text process --profile high_recall_german --input-file clinical_note.txt
phentrieve query --profile precise_english_query --text "patient shows..."
Acceptance Criteria:
A new --profile <profile_name> option is added to relevant CLI commands (initially query and text process).
Phentrieve loads profiles from phentrieve.yaml.
Options specified in the profile are used as defaults for the command.
Command-line arguments explicitly provided by the user override profile settings.
If a profile specifies a command, the --profile option should ideally only be accepted by that command (or an error/warning issued).
Clear error message if a specified profile is not found.
Documentation is updated to explain how to define and use profiles.
